Baking Soda vs. Baking Powder: What’s the Difference? ›

While both products appear similar, they're certainly not the same. Baking soda is sodium bicarbonate, which requires an acid and a liquid to become activated and help baked goods rise. Conversely, baking powder includes sodium bicarbonate, as well as an acid. It only needs a liquid to become activated.

Baking soda is 100 percent sodium bicarbonate, an alkaline salt compound that creates carbon dioxide gas when mixed with an acid. Baking powder, on the other hand, is a mixture of sodium bicarbonate and an acid like cream of tartar which requires moisture and heat to activate.

Baking powder: Baking powder can be used to replace baking soda, though not at a 1-to-1 ratio. Because the former is not as strong as the latter, it's important to use three times the amount of baking powder as baking soda. Be aware, a slightly bitter, off-putting taste might result from using that much baking powder.

Using the wrong leavening agent

If you accidentally add baking soda instead of baking powder to baked goods, they won't rise because there is not enough acid.

Baking powder is used to increase the volume and lighten the texture of baked goods. It works by releasing carbon dioxide gas into a batter or dough through an acid–base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture.

Baking soda and baking powder are both essential pantry staples for bakers. They have long shelf lives, but can they go bad? The answer is yes. Both baking soda and baking powder will eventually expire.

Baking soda is good indefinitely past its best by date, although it can lose potency over time. You can use a rule of thumb—two years for an unopened package and six months for an opened package. While old baking soda may not produce as much leavening action, it is still safe to eat.

Many recipes need both kinds of reactions to achieve the intended overall balance of flavor and texture, which is why you'll often see both baking soda and baking powder in a recipe. Even though the ingredients are both adding air during the baking process, they're complements, not substitutes.

For every teaspoon of baking powder, you'll want to substitute in ¼ tsp of baking soda with ½ tsp of cream of tartar. If you don't have any cream of tartar, you can also substitute one teaspoon of baking powder with a mixture of ¼ tsp of baking soda plus ½ tsp of either vinegar or lemon juice.

What Is Baking Powder? Baking powder is a two-in-one chemical leavening that combines a powdered alkali (sodium bicarbonate) with a powdered acid (originally, tartaric acid). When moistened in a dough or batter, a chemical reaction takes place that produces carbon dioxide gas, inflating cookies, cakes, and pancakes.

Why baking soda is not used in cakes? ›

Use of baking soda while baking or making cake, makes the cake taste bitter due to the formation of Sodium carbonate during heating. Hence, to neutralize the formed sodium carbonate and its bitter taste, we use tartaric acid. As an acid tartaric acid neutralizes the base effect of Sodium bicarbonate.

If a recipe calls for a tablespoon of baking powder, you'll want to substitute with a teaspoon of baking soda. You'll also want to add 2 teaspoons of vinegar or lemon juice to your batter.

Using Cornstarch and Baking Powder Interchangeably

Interestingly, cornstarch can be a component of homemade baking powder. If there's baking soda and cream of tartar in your pantry as well, you're in luck. You can actually create a substitute that's pretty close to what you'd buy off the shelf.

When to use which one. Baking soda is used in recipes that also include an acidic ingredient, such as cream of tartar, buttermilk, or citrus juice. Conversely, baking powder is typically used when the recipe doesn't feature an acidic ingredient, as the powder already includes the acid needed to produce carbon dioxide.

It's important not to use too much baking soda in recipes, as it can result in a metallic, soapy flavor. It is much more powerful than baking powder – you only need about 1/4 teaspoon baking soda per cup of flour to leaven baked goods.

Baking soda can be used with some water to remove the stains on the surface of the teeth. It can also be used with hydrogen peroxide to enhance its whitening effects. Baking soda can be used by individuals with regular toothpastes too. It is also used commercially in some teeth whitening products and toothpastes.

Baking soda is typically used for chewy cookies, while baking powder is generally used for light and airy cookies. Since baking powder is comprised of a number of ingredients (baking soda, cream of tartar, cornstarch, etc.), using it instead of pure baking soda will affect the taste of your cookies.

Baking soda is most commonly used in cookie and muffin recipes. Baking powder, however, already contains an acid and a base and has a more neutral taste, which works great when baking cakes and bread.

Baking soda

When added to dough, baking soda releases a carbon dioxide gas which helps leaven the dough, creating a soft, fluffy cookie.

What did you observe? The baking soda reacted faster with vinegar than baking powder did and also produced more bubbles. The baking powder also bubbled when vinegar was added, but the overall reaction was slower and the bubbles did not rise as high in the cup as they did with baking soda.
