Is Ammonium Carbonate available in the metro area? Apparently, in a google search, its also known as Bakers Ammonia. I don't need much, 2+ ounces mailorder seems a waste.
I grew up with a springerle recipe that used it ( a cookie, German, I think), and I'm wondering if it is available so I can revisit my childhood by baking this recipe.
Mom went to the local pharmacy for it ( I didn't grow up in MN)
