It is a white, crystalline powder. It is known for its versatility and its ability to react with acidic ingredients. It is a common household item used for a variety of purposes beyond just baking. Its simple composition makes it a reliable ingredient for many culinary and household tasks.
Baking soda is a fundamental ingredient for leavening baked goods. It also serves as a gentle abrasive for cleaning.
In baking, it is often combined with an acidic ingredient, such as buttermilk, yogurt, or lemon juice. This reaction creates carbon dioxide gas, which causes doughs and batters to rise, resulting in lighter and fluffier textures. For cleaning, a paste made with water can be used to scrub surfaces. It can also be placed in open containers to absorb odors in refrigerators or other areas. Its mild alkalinity makes it effective for neutralizing many types of smells.
