The GF Baking Powder 14oz from Bob's Red Mill is a game-changer in the baking world. This high-quality, gluten-free baking powder functions as a leavening agent, releasing carbon dioxide when combined with moisture and heat to cause doughs and batters to rise. Distinctively, it contains no added aluminum and utilizes monocalcium phosphate and sodium acid pyrophosphate instead of the commonly-used sodium aluminum phosphate or sodium aluminum sulfate, giving your baked goods a superior taste without a metallic aftertaste. Ensured of its purity, this product is produced and batch tested in a dedicated gluten-free facility.
