What Is Baking soda and How Can I Use It?

Wondering what to do with baking soda? This guide covers how to pick it, cook it, store it, and swap it, plus 4,703 recipes to put it to work.

Key Points

Sodium bicarbonate needs an acid like buttermilk, molasses or natural cocoa to power a rise.
About ¼ teaspoon per cup of flour is plenty; excess tastes soapy and darkens the crumb.
Replace 1 teaspoon baking powder with ¼ teaspoon soda plus ½ teaspoon cream of tartar.
Bake soda-leavened batters promptly; the gas starts escaping at room temperature.
Test an old box with vinegar: a strong fizz means it still works.

What is baking soda?

Baking soda is pure sodium bicarbonate, NaHCO₃, a white alkaline powder that does one chemical trick: meet an acid, release carbon dioxide. Those bubbles are the rise in a whole family of quick breads, cookies and pancakes.

The catch is that the acid has to come from somewhere in your recipe.

Buttermilk, yogurt, sour cream, molasses, brown sugar, honey, applesauce, lemon juice and natural cocoa all qualify. That is why Bo's Buttermilk Biscuits and Applesauce Banana Bread lean on soda: the acid is already in the bowl.

More than 4,700 recipes on Recipeland use it.

How the Rise Happens

The reaction starts the moment soda meets wet acid, at room temperature, not in the oven. So a soda-leavened batter is on the clock: mix it and bake it without long delays, or the gas escapes before the structure sets.

Dose matters more than people think. About ¼ teaspoon per cup of flour is the usual ceiling; past that, leftover alkalinity gives a soapy, faintly metallic taste and an oddly dark crumb.

That darkness is the other thing soda does. Alkaline batters brown faster, which is why a pinch shows up in cookie doughs like Jumbo Chocolate Chip Cookies beyond what leavening alone would need, and why pretzels get a soda bath before baking.

What Activates It (and What Quietly Doesn't)

Natural cocoa powder is acidic and activates soda. Dutch-process cocoa has been alkalized and does not.

Swap one cocoa for the other in an old recipe and the rise changes underneath you; flat, dense chocolate cake is the classic symptom. Match the cocoa the recipe names.

If a recipe has no acidic ingredient at all, soda is the wrong tool. Reach for baking powder, which packages the acid and the base together and waits for heat.

Trading With Baking Powder

The two convert in both directions, just not 1:1, because soda is three to four times stronger.

To replace 1 teaspoon of baking powder, use ¼ teaspoon of baking soda plus ½ teaspoon of cream of tartar. The reverse trade is rarely worth making; baking powder's built-in acid changes both flavor and browning.

There is no substitute that does nothing to flavor. Self-rising flour hides baking powder and salt inside, which is fine as long as you stop adding your own.

Buying and Keeping It

Any brand is the same compound; buy whatever is cheap. Americans baked with it through the 1800s, when it sold under the name saleratus in bright red wrappers with a free recipe card inside, and the compound itself has not changed since.

Keep it sealed and dry. An open box happily absorbs moisture and kitchen odors, which is exactly why it works as a fridge deodorizer and exactly why a deodorizing box should never go back into your cookies.

An opened box stays reliably potent for a few months of baking, less in a humid kitchen. To check an old one, stir ½ teaspoon into a splash of vinegar: a vigorous fizz means it is still working, a weak one means it is now a cleaning product.
