So I ordered some food grade Ammonium Carbonate today to try in some of the colonial recipes I have for biscuits and for cookies. As an ingredient it was available in the 18th century. Don't know how far out "on the frontier" it would have been found. I'm especially interested in cookies made with molds as I've been told that AC is important for those sorts of cookies to retain fine detail from the mold when being baked.
