A&H Baking Soda (sodium bicarbonate) is a fine white powder used primarily as a leavening agent in baking and as a convenient household cleaner. In baking it reacts with acidic ingredients to produce carbon dioxide, helping batters and doughs rise. Around the home it can neutralize odors, gently scrub surfaces, and freshen carpets or refrigerators. Store in a cool, dry place and keep the package sealed when not in use. For specific ingredient or allergen questions, consult the product packaging or contact Broadway Food in Spokane, Texas.
