What Does Baking Soda In Biscuits Do?
Baking soda in biscuits helps them rise and become light and fluffy. When combined with an acid, such as buttermilk or cream of tartar, baking soda produces carbon dioxide gas, which creates air pockets in the dough. As the biscuits are baked in the oven, the gas expands, causing the biscuits to puff up. Baking soda also helps to neutralize the acidity in acidic ingredients like buttermilk, which helps to create a balanced flavor in the biscuits.
