I have a recipe from my mother's collection which is for "Mamie Eisenhower's Fudge." It used evaporated milk, so thought I'd pass it along. It's quite old, and I'm going to type it exactly as it appears on her recipe card:
Put granulated sugar in a sauce pan. Add evaporated milk, salt and 2 tablespoons of butter. Let come to a boil and boil 6 minutes. Cut up chocolate fine and add chocolate chips and marshmallow creme Pour hot liquid on above and beat and beat until thick. Add chopped nut meats.
Pour into 8 x 8 x 2 inch pan which has been greased with butter.
