Baker's Ammonia (Ammonium Carbonate) 2.7 oz., jar

Product Code: 6007-0600

Baker's Ammonia (Ammonium Carbonate) is a leavening ingredient called for in many old fashioned recipes. It is also called "hartshorn".

Baker's Ammonia is used to make extra-crisp cookies or crackers. Unlike baking powder or soda, it does not leave an alkaline off-flavor in baked goods. It is not used for leavening in cakes or other large-volume items as the ammonia gas will not evaporate entirely.

Note:  You will notice an odor of ammonia while baking, but this will quickly dissipate and the finished baked product will not have an odor or taste of ammonia.

Because Baker's Ammonia has a tendency to evaporate when exposed to air, it should be stored in a jar with a tight cover.  It will not spoil, but will "disappear" if not stored properly.

I always use this product for my Springerle cookies and other cookie recipes from Europe and America. It is a terrific product to use instead of baking powder. Impression cookies bake with the impression intact.

I'm glad to see that it comes in crushed form, and easier to find. We used to go to the pharmacy to get hartshorn ,then they would crush it in a motar and pedestal. Then mom would make cookies with the hartshorn and anise oil. They are an old German recipe and they are the best.

This product is used in making old fashioned German cookies, the recipe for which I received from my husband's mother. It is sometimes called Pepper Nuts in America, but nothing like the kind you may see at Christmastime in the stores. They look like little derby hats when baked.
