Ammonia is a chemical compound that contains nitrogen and hydrogen. It has a crystalline form, white color, and its smell is strong and penetrating, causing coughing when inhaled.

It is used in the food industry, in confectionery, and in baking as a leavening agent in doughs. It is activated by heat and behaves like baking soda and baking powder. Its unpleasant smell dissipates after baking.

A small amount of it (1/2 tsp) is enough to enhance the flavor and crunchiness of sweet creations. Many recipes for Easter cookies require ammonia.
