Baking Powder Overview

Baking powder is a chemical leavening agent made from baking soda, an acid, and starch (usually cornstarch). While used in very small amounts, the added starch makes baking powder a high-carb ingredient by classification. It is not ideal for strict keto or diabetic-focused baking unless used sparingly.
