5 T flour and 1 cup milk
mix together in a saucepan and cook until thickened, stirring constantly. It will be very thick. Cool thoroughly.
Beat together until fluffy. This takes a few minutes, about 5.
1 cup shortening, 1 cup sugar, 1/2 tsp vanilla
Then add the flour mixture and continue to beat until fluffy. Mix until you cannot taste the granulated sugar in the frosting.
We sometimes add powdered sugar to this to make it more useable. Especially if it is humid—like right now. 1-2 cups to help set it up is all you need.
