Ammonia Cookies

Jenan Madden, the manager of a book store in Seattle, shared this recipe with The Times. She acquired it as a child from a favorite baby sitter. “The taste is great,” she said. “And it’s fun telling people what they are called.” (Ammonia cookies are in fact made with ammonium carbonate, a form of baking soda, not cleaning ammonia, which is poisonous.)
