Why is Baking Soda in Ice Cream? Unveiling the Science Behind Smoother, Richer Frozen Desserts

It’s a question that might have crossed your mind while indulging in a scoop of your favorite ice cream, or perhaps while perusing an ingredient list: why is baking soda in ice cream? You might even have tried making homemade ice cream, and a recipe called for a tiny pinch of this common pantry staple, leaving you scratching your head. I certainly remember that feeling. I’d always associated baking soda with making cookies spread and rise, or for cleaning out the fridge. So, its presence in something as delicate and creamy as ice cream seemed, well, a bit counterintuitive. Yet, there it is, often lurking in small quantities, playing a surprisingly crucial role. The short answer is that baking soda, in very specific, carefully measured amounts, is often used in ice cream to help achieve a smoother, richer texture and to balance flavors, particularly when using acidic ingredients.

The Surprising Role of Baking Soda in Your Frozen Delight

Let's dive deeper into this culinary conundrum. While you might not see it listed as a primary ingredient in every ice cream recipe, its presence, even in trace amounts, is often deliberate and beneficial. Baking soda, chemically known as sodium bicarbonate (NaHCO₃), is a leavening agent. However, in the context of ice cream, its leavening properties are not the main objective. Instead, its alkaline nature and its ability to react with acids are what truly shine, leading to a more desirable final product. This might sound a bit scientific, but bear with me, as understanding the 'why' behind this ingredient can elevate your appreciation for your favorite frozen treat and even empower your own ice cream-making endeavors.

My personal journey with understanding baking soda in ice cream began when I started experimenting with dairy-free ice creams. Many vegan recipes rely on plant-based milks and ingredients that can sometimes have a slightly off-putting flavor or a less-than-ideal texture. I noticed that several well-regarded vegan ice cream recipes incorporated a small amount of baking soda, and the results were undeniably superior. This sparked my curiosity, pushing me to research the underlying scientific principles. What I discovered was a fascinating interplay of chemistry and culinary art.

Think about the typical ingredients in ice cream: milk, cream, sugar, and flavorings. These are generally neutral or slightly acidic. However, when you start introducing other components, especially in homemade ice cream, the pH balance can shift. This is where baking soda often steps in. Its primary function in ice cream is not about making it rise or puff up, as it does in baked goods. Instead, its subtle chemical reactions contribute to texture and flavor in ways that are quite remarkable. It’s a testament to how even the most common household ingredients can have complex and nuanced applications in the kitchen.

Understanding the Chemistry: Baking Soda's Alkaline Power

At its core, baking soda is an alkaline substance. This means it has a pH level greater than 7. In contrast, many common food ingredients, like fruits, coffee, or even milk to some extent, are acidic, meaning they have a pH level less than 7. The interaction between an acid and a base (like baking soda) is a chemical reaction that produces water and a salt. In baking, this reaction is often harnessed to create carbon dioxide gas, which causes doughs and batters to rise. But in ice cream, the goal is different.

When baking soda is added to an ice cream base, its alkaline nature can help neutralize any unwanted acidity. This is particularly relevant when using ingredients like buttermilk, sour cream, certain fruit purees, or even cocoa powder, which can contribute to a tart or slightly bitter flavor profile. By counteracting these acidic notes, baking soda can help create a more balanced, mellow, and richer taste. It essentially smooths out the flavor, allowing the primary sweetness and desired flavorings to come through more clearly and pleasantly.

I recall one instance where I was making a homemade lemon-flavored ice cream. The recipe called for a significant amount of lemon juice, and while the citrus flavor was vibrant, the ice cream ended up with a slightly sharp, almost curdled-like tang that wasn't entirely appealing. I experimented by adding a tiny pinch of baking soda to a second batch. The difference was astonishing. The harsh acidity was mellowed, and the creamy, sweet lemon flavor was more pronounced and enjoyable. It was a small change, but it made a world of difference in the overall taste and mouthfeel.

The science behind this lies in the neutralization reaction. When the sodium bicarbonate (baking soda) encounters an acid (like citric acid from the lemon juice), it reacts to form sodium citrate, water, and carbon dioxide. While the carbon dioxide production is minimal at the low temperatures of ice cream making and freezing, the formation of sodium citrate alters the overall pH of the mixture, making it less acidic. This subtle shift can have a significant impact on how we perceive the flavor and texture.

Enhancing Texture: The Key to Creaminess

Beyond flavor, baking soda plays a crucial role in improving the texture of ice cream. One of the most common challenges in ice cream making, both at home and commercially, is the formation of ice crystals. Large, chunky ice crystals lead to a grainy, icy texture, which is the antithesis of smooth, luscious ice cream. Baking soda can help combat this.

How does it do this? It’s a bit indirect. By altering the pH of the ice cream base, baking soda can affect how other ingredients interact and how the mixture freezes. Specifically, it can influence the proteins in the dairy or non-dairy base. In a slightly more alkaline environment, proteins tend to be more stable and less likely to coagulate or clump together. This improved stability helps to create a smoother emulsion, meaning the fat and water components are better dispersed and less likely to separate upon freezing.

Furthermore, the slight increase in pH can also impact the freezing point of the ice cream base. While not as significant as sugar or alcohol, changes in pH can subtly influence how the water in the mixture freezes. A more alkaline environment might, in some cases, contribute to the formation of smaller, more manageable ice crystals, leading to a smoother overall texture. It's a delicate balance, and too much baking soda can lead to undesirable soapy or metallic off-flavors, so precise measurement is key.

I've often heard bakers and ice cream makers refer to baking soda as a "texture enhancer" in certain applications. In ice cream, it acts as a subtle manipulator of the freeze-thaw cycle and the overall crystallization process. It’s not a primary thickener or emulsifier like egg yolks or stabilizers, but its subtle chemical influence contributes to a more refined mouthfeel. When you achieve that incredibly smooth, melt-in-your-mouth consistency, baking soda might just be a silent, unsung hero behind the scenes.

Baking Soda and Dairy-Free Ice Cream: A Match Made in Heaven?

As I mentioned earlier, my personal discovery of baking soda's utility in ice cream was closely tied to the world of dairy-free frozen desserts. Vegan ice creams often face unique challenges. Plant-based milks, such as almond, soy, or oat milk, have different protein structures and fat profiles compared to dairy milk and cream. These differences can sometimes result in ice creams that are icier, less rich, or have subtle off-flavors.

One common issue with some plant-based milks is a slightly beany or grassy undertone. Baking soda, with its alkaline properties, can help neutralize these subtle off-flavors, making the ice cream taste cleaner and more neutral. This allows the intended flavorings, whether it's chocolate, vanilla, or fruit, to shine without competing with background vegetal notes.

Additionally, the protein structure in plant-based ingredients can behave differently during freezing. Without the specific proteins found in dairy (like casein and whey), achieving that desirable smooth, creamy texture can be more challenging. Baking soda can, as discussed, help stabilize these alternative proteins and fats, leading to a better emulsion and a smoother freeze. It’s not a magic bullet, of course, and good quality plant-based milks, fats (like coconut cream or cashew butter), and stabilizers are still essential. However, that small addition of baking soda can often be the secret ingredient that elevates a good dairy-free ice cream to a truly great one.

When I recommend recipes or troubleshoot issues with friends who are new to vegan ice cream making, I always emphasize the importance of precise measurement when using baking soda. A tiny pinch is often all that's needed. Too much, and you risk that soapy taste that can ruin an otherwise delicious dessert. It’s a delicate dance of chemistry, but the payoff in terms of texture and flavor is often well worth the effort.

When is Baking Soda Used in Ice Cream Recipes?

So, you might be wondering, when exactly do ice cream recipes call for baking soda? It's not a universal ingredient, and its inclusion is often dependent on the specific flavor profile and the types of ingredients used. Here are some common scenarios where you might find baking soda on the ingredient list:

Recipes with acidic fruits or juices: As seen in my lemon ice cream example, recipes featuring ingredients like berries, citrus fruits, passionfruit, or even rhubarb might include baking soda to balance the tartness.
Recipes using cultured dairy products: If a recipe calls for ingredients like buttermilk, crème fraîche, or sour cream, which have a natural tang, a small amount of baking soda can help mellow out that acidity.
Recipes with cocoa powder: Natural cocoa powder is acidic. Dutch-processed cocoa powder, on the other hand, has been treated to be more alkaline. Recipes using natural cocoa powder might incorporate baking soda to neutralize its acidity, leading to a richer, less bitter chocolate flavor and a deeper color.
Dairy-free or vegan ice creams: As discussed, it's often used to improve texture and neutralize subtle off-flavors in plant-based milks and ingredients.
Certain custard-style ice creams: In some traditional custard bases, a tiny amount of baking soda might be used to help stabilize the egg proteins and contribute to a smoother texture.
Recipes aiming for a specific "old-fashioned" or unique flavor profile: In rare cases, a minuscule amount might be added for a subtle flavor nuance, though this is less common and relies heavily on precise ratios.

It's important to note that the quantity of baking soda used is almost always very small – often just an eighth or a quarter of a teaspoon, sometimes even less, for a standard batch of ice cream. This is because its flavor can be overpowering if used in excess. The goal is a subtle enhancement, not a noticeable taste of baking soda itself.

The Delicate Balance: Too Much of a Good Thing

While baking soda can offer significant benefits to ice cream, it’s crucial to understand that its effectiveness hinges on precise measurement. Using too much baking soda can have detrimental effects on both the flavor and texture of your ice cream. I cannot stress this enough: start with the smallest amount called for in a recipe, or even less, and taste as you go if you’re experimenting.

Flavor Concerns: The most immediate and noticeable negative impact of too much baking soda is an unpleasant, soapy, or metallic taste. This off-flavor is a direct result of the alkaline nature of baking soda. Our palates are sensitive to high pH levels, and a noticeable "soapy" taste is a clear indicator that the balance has been tipped too far. This can mask the intended flavors of the ice cream and make it quite unpalatable. I’ve unfortunately experienced this myself when I first started playing with baking soda in my own recipes – let’s just say it wasn’t my proudest culinary moment, and the ice cream went straight into the compost bin!

Texture Issues: While baking soda can help prevent ice crystal formation in the right amounts, too much can actually lead to other textural problems. An excessively alkaline base can sometimes cause proteins to break down too much, leading to a gummy or mushy texture rather than a smooth one. It can also interfere with the emulsification process if other emulsifiers (like egg yolks) are present, potentially causing the fat to separate and creating an oily mouthfeel. The desired effect is smoothness, not a strange, gummy consistency.

Color Alterations: In some recipes, particularly those involving chocolate or fruit, excessive baking soda can lead to undesirable color changes. For instance, in chocolate ice cream, a high pH can cause the cocoa solids to oxidize and turn a reddish-brown color, rather than the deep, rich brown associated with good chocolate. In recipes with anthocyanin-rich fruits (like blueberries or raspberries), a high pH can shift their natural purple or red hues towards a more muted, blueish, or even greenish-brown color.

Therefore, when a recipe calls for baking soda, it’s typically a very small quantity, precisely measured. If you are adapting a recipe or experimenting, it is always best to start with a very minimal amount, perhaps just a few grains, and see how it affects the taste and texture. Remember, baking soda is a potent ingredient, and a little goes a very long way in the delicate world of ice cream.

The Science of Smoothness: How Baking Soda Contributes

Let's revisit the science behind why baking soda contributes to smoothness in ice cream. It's a fascinating interplay of pH, protein, and fat interactions. The primary goal in ice cream making, besides delicious flavor, is to minimize the formation of large ice crystals. These crystals are the culprits behind that dreaded grainy texture.

Here's a more detailed breakdown:

pH Adjustment and Protein Stability: Dairy and non-dairy bases contain proteins. These proteins play a role in the structure and texture of the final product. Baking soda, being alkaline, raises the pH of the ice cream base. In a neutral or acidic environment, proteins can sometimes denature and aggregate (clump together) during the freezing process, leading to a less smooth texture. However, in a slightly more alkaline environment, proteins tend to remain more dispersed and stable. This better dispersion helps create a more uniform matrix as the ice cream freezes, trapping smaller ice crystals and contributing to a smoother mouthfeel. This is analogous to how baking soda helps create a tender crumb in cakes by interacting with gluten proteins.
Improved Emulsification: Ice cream is essentially an emulsion, where tiny fat globules are dispersed throughout a water-based mixture. Baking soda can subtly influence the stability of this emulsion. By affecting the surface charges of the fat globules and other components, it can help keep them evenly distributed. A well-emulsified mixture is less prone to separating during freezing and churning, which further contributes to a smoother, more homogenous texture.
Interference with Ice Crystal Growth: While baking soda itself doesn't act as a primary ice crystal inhibitor like sugar or alcohol, its influence on the overall matrix of the ice cream can indirectly affect ice crystal formation. By promoting a more stable protein network and better emulsification, it helps create a structure that can accommodate smaller ice crystals. Furthermore, the slight alteration in the freezing point of water due to pH changes, though minor, can also contribute to smaller, more numerous ice crystals rather than large, jagged ones.
Neutralizing Acidity: In recipes where acidic ingredients are used, baking soda neutralizes these acids. This not only improves flavor but can also prevent the acids from interfering with the gelling or thickening properties of other ingredients like starches or gums if they are used as stabilizers. This ensures a more consistent and desirable texture.

Think of it like this: when you're building something, you want all your building blocks to be uniform and well-placed. Baking soda helps ensure that the "building blocks" of your ice cream – the water molecules forming ice crystals, the fat globules, and the proteins – are arranged in a way that creates a smooth, even structure, rather than a lumpy, uneven one.

Baking Soda in Commercial Ice Cream Production

While you might encounter baking soda more readily in artisanal or home recipes, its use in commercial ice cream production is also worth noting. Large-scale ice cream manufacturers often use a complex blend of ingredients and stabilizers to achieve consistent quality and desired textures. Baking soda, in very small, controlled amounts, can be one of these tools.

Commercial ice cream production involves sophisticated machinery and precise control over temperature and processing. The need for consistent texture and flavor is paramount. Baking soda can be used to:

Standardize pH: Different batches of raw ingredients (milk, cream) can have slightly varying pH levels. Baking soda can be used to bring the base to a consistent, optimal pH for processing and freezing, ensuring uniformity across production runs.
Enhance Stability: In the high-speed world of commercial ice cream making, stability is key. Baking soda's ability to help stabilize proteins and emulsions contributes to ice cream that holds its shape well and has a desirable melt rate.
Flavor Balancing in Large Batches: When dealing with vast quantities of ingredients, subtle flavor imbalances can become more pronounced. Baking soda can help ensure a balanced, clean flavor profile that appeals to a broad consumer base.
Cost-Effective Texture Improvement: Compared to some specialized stabilizers, baking soda is a very inexpensive ingredient. When used judiciously, it can provide a texture-enhancing benefit at a low cost, making it an attractive option for manufacturers.

However, it's also true that many commercial ice creams rely more heavily on other stabilizers and emulsifiers (like guar gum, carrageenan, locust bean gum, mono- and diglycerides) to achieve their characteristic texture. The use of baking soda in commercial settings is often a subtle, supporting role rather than a primary one. You'll rarely see it listed prominently, and when it is, it's in very small quantities, often alongside other "anti-caking agents" or "acidity regulators."

DIY Ice Cream: When and How to Use Baking Soda

For those venturing into the delightful world of homemade ice cream, understanding when and how to use baking soda can be a game-changer. As we've discussed, it's not a necessary ingredient for every ice cream, but it can be incredibly beneficial in specific scenarios. If you're a beginner, I highly recommend following well-tested recipes that specifically call for it. This will give you a baseline for how it should be used.

Here’s a guide for incorporating baking soda into your DIY ice cream endeavors:

1. When to Consider Using Baking Soda:

You're making a recipe with acidic fruits or juices (e.g., raspberry, lemon, lime).
Your recipe includes ingredients like buttermilk, yogurt, or sour cream.
You're using natural cocoa powder for a chocolate ice cream and want a richer flavor and color.
You're making a dairy-free ice cream and want to improve texture and neutralize potential off-flavors from plant-based milks.
You notice your ice cream base tastes a bit too sharp or tart for your liking.

2. How to Measure Accurately:

Use a Micro Spoon or Scale: Baking soda is potent. Standard measuring spoons can still be too large for the tiny amounts needed. A set of micro measuring spoons (measuring in 1/16 or 1/32 of a teaspoon) is ideal. Alternatively, a digital kitchen scale that measures in grams or even milligrams is the most precise.
Start Small: If a recipe calls for 1/4 teaspoon, try using just 1/8 teaspoon first. If you're experimenting without a recipe, start with just a few grains.
Dissolve Thoroughly: It’s often best to dissolve the baking soda in a small amount of the liquid (like a tablespoon of milk or water) from your recipe before adding it to the main base. This ensures it's evenly distributed and doesn't create little pockets of alkalinity. Stir until fully dissolved.

3. When to Add Baking Soda:

Typically, baking soda is added during the mixing of the ice cream base, before it’s chilled or churned. Add it along with your other dry ingredients or dissolve it in a small amount of liquid and then incorporate it into the base.

4. How Much is Too Much? (The Taste Test is Crucial!):

For a standard batch (about 1 quart): Generally, no more than 1/4 teaspoon of baking soda is needed. Often, 1/8 teaspoon or even less is sufficient.
Always Taste: After adding the baking soda and mixing it thoroughly, taste a small amount of your base (if it's safe to consume raw, like a pasteurized dairy base). You should not detect any soapy or metallic flavor. The flavors should be balanced, not sharp or overly tangy.

5. What to Do if You Add Too Much:

Unfortunately, it's very difficult to fully correct an ice cream base that has too much baking soda. The soapy flavor can be quite persistent. Your best bet might be to:

Dilute it: Make a larger batch of ice cream base without baking soda and blend the two together. This will reduce the concentration of baking soda but will also dilute your other flavors.
Add more acid: Carefully add a tiny bit more of the acidic ingredient (like lemon juice or vinegar) to try and neutralize the alkalinity. This is tricky and can throw off the flavor balance.
Start over: In some cases, it might be best to discard the batch and start again, paying close attention to measurements.

My personal advice for DIY ice cream makers? Don't be afraid of baking soda, but respect its power. Treat it as a potent spice or a delicate flavor enhancer, not a bulk ingredient. When used correctly, it can transform your homemade ice cream from good to spectacular.

Frequently Asked Questions About Baking Soda in Ice Cream

Why does my homemade ice cream taste soapy?

The most common reason for a soapy taste in homemade ice cream is the presence of too much baking soda. Baking soda, or sodium bicarbonate, is an alkaline substance. When used in excessive amounts, its inherent alkaline flavor becomes detectable to our palates. This soapy or sometimes metallic taste is a clear indicator that the pH balance of your ice cream base has been significantly shifted towards alkalinity. It's a flavor that can be quite persistent and difficult to mask. If you've encountered this issue, it's crucial to re-evaluate the amount of baking soda used in your recipe. For most standard ice cream recipes (around a quart), you’ll typically need only a tiny pinch, often less than 1/8th of a teaspoon. Always measure carefully, using micro-spoons or a precise scale if possible, and err on the side of using less. You can always add a tiny bit more if needed, but it's nearly impossible to remove if you've added too much.

Beyond baking soda, other factors can sometimes contribute to off-flavors that might be perceived as soapy, though less commonly. For example, certain stabilizers or emulsifiers used in very high concentrations might impart unusual tastes, or if ingredients have gone slightly rancid, they can develop off-flavors. However, in the context of baking soda being an ingredient, an excessive amount is almost always the culprit behind that distinct soapy sensation. Remember, baking soda is meant to be a subtle enhancer, not a primary flavor component, and its use is often specific to recipes involving acidic ingredients or certain dairy-free bases.

Can I substitute baking soda with baking powder in ice cream?

No, you generally cannot substitute baking powder for baking soda in ice cream recipes, or in most baking recipes for that matter, with good results. While both are leavening agents, they have different compositions and react differently. Baking soda is pure sodium bicarbonate. Baking powder, on the other hand, is a complete leavening system that contains sodium bicarbonate (baking soda) *plus* an acid (like cream of tartar or sodium aluminum sulfate) and a filler (like cornstarch). This means baking powder already contains its own acid. If you add baking powder to a recipe that already has acidic ingredients, you'll have an overreaction, and the leavening power will be spent too quickly, potentially leading to a bitter or metallic taste from the excess acid component in the baking powder.

In the context of ice cream, where baking soda is used for its alkalinity to neutralize acids and improve texture, not for leavening, substituting baking powder would completely undermine its intended purpose. You would be introducing a different chemical reaction and potentially adding unnecessary acidity. Baking powder's primary role is to create carbon dioxide gas for rising in baked goods, which is not the goal in ice cream. Therefore, if a recipe calls for baking soda in ice cream, it's best to use baking soda. If you absolutely don't have baking soda and the recipe calls for it, it's often better to omit it entirely unless you're very experienced with ingredient substitutions and understand the chemical implications, which is rarely the case for ice cream.

Why is baking soda sometimes used in chocolate ice cream?

Baking soda is often used in chocolate ice cream recipes primarily to manage the acidity of natural cocoa powder and to enhance the richness and color of the chocolate flavor. Natural cocoa powder, as opposed to Dutch-processed cocoa powder, is acidic. This acidity can sometimes lead to a slightly bitter or sharp chocolate flavor, and it can also affect the color, giving it a more reddish-brown hue. When baking soda, an alkaline substance, is added to the ice cream base containing natural cocoa powder, it reacts with these acids.

This neutralization process has several beneficial effects for chocolate ice cream: Firstly, it mellows out any harsh bitterness or tang from the cocoa, allowing the deeper, richer chocolate notes to emerge more prominently. It creates a smoother, more balanced chocolate flavor profile. Secondly, by raising the pH of the mixture, baking soda can help deepen the color of the chocolate. The anthocyanins present in cocoa are sensitive to pH; in an alkaline environment, they tend to appear a richer, darker brown rather than a reddish-brown. Finally, as we've discussed for ice cream in general, baking soda can also contribute to a smoother texture by influencing protein stability and emulsification, which is always desirable in a rich dessert like chocolate ice cream. So, when you see baking soda in a chocolate ice cream recipe, it’s often a deliberate choice to achieve a more intense, balanced, and visually appealing chocolate experience.

Does baking soda affect the freezing point of ice cream?

Yes, baking soda can have a subtle effect on the freezing point of ice cream, though it's generally not the primary factor. The freezing point of water is 0°C (32°F). However, when substances are dissolved in water, they lower the freezing point. This phenomenon is known as freezing point depression, and it's a colligative property, meaning it depends on the number of solute particles in the solvent. Sugar is a major contributor to lowering the freezing point in ice cream, which is why ice cream remains scoopable even at temperatures below freezing.

Baking soda (sodium bicarbonate) is a solute, so when it dissolves in the water within the ice cream base, it does contribute to lowering the freezing point. However, the amount of baking soda typically used in ice cream recipes is very small (often 1/8 to 1/4 teaspoon per quart). Compared to the significant amounts of sugar and other dissolved solids like milk solids and flavorings, the contribution of baking soda to freezing point depression is relatively minor. Its primary roles in texture and flavor are achieved through chemical interactions (like pH adjustment) rather than solely through its effect on the freezing point. So, while it does have an effect, it's usually considered secondary to other ingredients when discussing why ice cream stays soft.

Can I use baking soda if I'm lactose intolerant or making a vegan ice cream?

Absolutely! Baking soda can be particularly beneficial in lactose-free and vegan ice cream recipes. As we've touched upon, plant-based milks (like almond, soy, oat, or coconut milk) and other vegan ingredients can sometimes present unique textural challenges or subtle off-flavors compared to dairy. Baking soda can help address these issues.

Here's why it's a good option for vegan and lactose-free ice creams: 1. Flavor Neutralization: Some plant-based milks can have a slightly beany, grassy, or otherwise "green" flavor. Baking soda's alkaline nature can help neutralize these subtle off-notes, leading to a cleaner, more neutral base that allows the primary flavors of your ice cream (like chocolate, vanilla, or fruit) to stand out more clearly. 2. Texture Improvement: Achieving a smooth, creamy texture in vegan ice cream can be trickier due to the absence of dairy proteins and fats. Baking soda can help stabilize the proteins and fats present in vegan bases, improving the emulsion and contributing to a smoother, less icy texture as the ice cream freezes. It helps create a more homogenous structure. 3. Acidity Balance: Many vegan recipes might incorporate acidic ingredients (like fruit purees or even some plant-based yogurts) to add tang or complexity. Baking soda helps balance this acidity, preventing the ice cream from tasting overly tart and contributing to a more mellow flavor profile.

When using baking soda in vegan or lactose-free ice cream, the same rules apply: measure carefully, start with small amounts, and ensure it’s fully dissolved. It's a powerful tool for enhancing the quality of dairy-free frozen desserts.

Conclusion: The Humble Helper in Your Ice Cream

So, the next time you savor a spoonful of rich, creamy ice cream, take a moment to appreciate the subtle science at play. Baking soda, that unassuming box in your pantry, plays a surprisingly significant role.
