MARY ANN PAN, MARY ANN CUPS
A Mary Ann Pan is a cake pan with a convex bottom. After the cake is baked and turned out, you have a cake with a hollowed out top which may then be filled with fruit, cream, ice cream, etc. Also called Mary Ann Tin.
Mary Ann Cups are a set of nested measuring cups.
I do not know who Mary Ann was, or if they are both named for the same person. I welcome any stories about either of these Mary Anns.
