What Baking Soda Is and How It Works
Baking soda is a leavening agent and mild alkali used in baking. It reacts with acids to release carbon dioxide, helping dough rise. In its pure form it is a finely granulated powder of sodium bicarbonate. When combined with an acidic ingredient such as yogurt, vinegar, lemon juice, or buttermilk, you get the chemical reaction that lifts cakes and cookies. The Bake In Oven team notes that this reaction is most effective when the batter is heated, so provide enough moisture and heat for the gas to form and expand. Because it is a base, baking soda can also influence browning and crumb by raising the
In Briefer Terms:** Baking soda is a type of leavening agent used in baking that works with acids to lift doughs and cakes while also influencing color and texture.
Frequently Asked Questions
What is baking soda used for in baking?
Baking soda acts as a leavening agent that helps batters rise when an acid is present. It also influences crumb, texture, and browning by raising the pH. For best results, pair it with an appropriate acid source in recipes.
In baking, baking soda helps batter rise when there’s acid present and also affects texture and browning.
Can I substitute baking powder for baking soda?
Yes, but you must provide an acid and adjust the liquid balance. Baking powder contains both base and acid, so substituting requires reducing liquids and adding an acid source to avoid over-leavening.
You can substitute baking powder when you balance acids and liquids, but it won’t behave exactly like baking soda in every recipe.
How should baking soda be stored?
Store baking soda in an airtight container in a cool, dry place away from strong odors. Moisture can cause clumping and reduce effectiveness.
Keep it airtight in a cool, dry spot and check for clumps before use.
Is baking soda safe to ingest?
In normal culinary amounts, baking soda is considered safe for consumption. Avoid excessive use, which can affect taste and health. If you have medical concerns, consult a healthcare professional.
Used in typical cooking amounts, baking soda is generally safe; avoid taking large amounts.
Can baking soda remove odors?
Yes, baking soda can help neutralize odors in refrigerators, shoes, and carpets. It works best when left to sit for a while before cleaning or vacuuming.
It helps neutralize smells when used as a deodorizing powder or paste, then wiped away or vacuumed.
Does baking soda expire?
Baking soda does not spoil like food, but it loses potency over time. A fizz test with water can confirm activity; replace if fizz is weak.
It can lose potency over time; perform a quick fizz test and replace if needed.
