When I was a child my mother use to make a poor man's cake and she would put potato frosting on it. This frosting was not overly sweet, I have found a recipe for the cake. However, no one seems to have ever heard of potato frosting.
Well, this is a new one on me but I am sure it could be done.
I was a full time working mother and I remember when I first used instant potato granules (1950's) - I threw out the first package as I felt that I may be giving my family something "artificial". No Internet to investigate - how things have changed!
I later learned that instant mashed potatoes could be used in many different ways but my family loved meatloaves, stuffed peppers and some casseroles topped with these (when no fresh mashed potatoes were available).
Yes I know this recipe my mother made a Christmas cake out of this potato icing we were amazed but it was so delicious. Think she had to use this during the war as she was a cook in the army.
lindatlbry, do you remember ingredients to the recipe? TIA
