Baking Soda in Cooking and Baking
Baking soda is primarily used as a leavening agent. When combined with acidic ingredients like vinegar, lemon juice, or yogurt, it produces carbon dioxide gas, which helps dough rise, resulting in soft, airy, and fluffy baked goods.
Baking Soda vs Baking Powder
Although often confused, baking soda and baking powder serve different purposes. Baking powder contains both an acid and a base, making it ready to use in recipes without additional acidic ingredients. Using baking soda incorrectly can lead to a bitter taste or uneven rising in baked goods.
Common uses in baking:
-
Baking soda for bread, cakes, cookies, and muffins
-
Sodium bicarbonate in recipes for fluffy pancakes and waffles
-
Neutralizing acidic ingredients in chocolate or buttermilk-based desserts
Household Cleaning and Deodorizing Uses
Baking soda is a safe, natural, and eco-friendly cleaning agent. Its mild abrasiveness and pH-neutralizing properties make it perfect for:
-
Kitchen cleaning: countertops, ovens, pans, sinks, and stovetops
-
Bathroom cleaning: tubs, tiles, sinks, and faucets
-
Odor removal: refrigerators, trash bins, carpets, and shoes
-
Stain removal: coffee, grease, wine, and pet stains from fabrics
DIY Cleaning Hacks
Mixing baking soda with vinegar or lemon juice creates a fizzy reaction that helps lift tough stains and grime. It is an ideal alternative to harsh chemical cleaners, making it safe for homes with children or pets.
