Almost Twinkie Filling
Source of Recipe
1/4 pound uncoloured margarine
1/2 cup Crisco shortening
1 cup sugar
3/4 c evaporated milk
1 teaspoon vanilla
Put all in a deep bowl and beat with electric mixer for 8-10
minutes., till fluffy and no trace of grittiness remains. Test by
rubbing some of the mixture between thumb and finger.
I have used this recipe in a jelly roll, along with a thin layer
of raspberry jam. Delicious. It is excellent for writing messages
on cakes, and it freezes very well.
