Ammonium bicarbonate—also known as baker’s ammonia—is a traditional leavening agent used in baking to produce light, crisp textures. This white, crystalline powder decomposes completely into carbon dioxide and ammonia when heated, helping doughs rise without leaving any aftertaste or residue. It’s ideal for thin, dry baked goods such as European-style cookies, crackers, and biscuits, where a delicate crumb and crisp finish are desired.
Unlike baking powder or baking soda, ammonium bicarbonate is highly effective in recipes that do not require long baking times or high moisture content. Its rapid release of gas results in a clean rise and neutral flavour, making it a preferred choice among pastry professionals and artisan bakers.
For best results, use in well-ventilated ovens and avoid recipes with high moisture or thickness, as any unbaked ammonia may cause off-notes. Store in an airtight container in a cool, dry place to preserve potency and prevent clumping due to humidity.
