Can anyone tell me why when I make this filling it turns grainy. The recipe calls for crisco, sugar, butter, 1 egg white, vanilla and a little hot milk. directions are to beat well. I do this but it never turns out smooth, always grainy. What am I doing wrong?
What is this "filling" for? What is the direction for its preparation? Is it just mixing all the ingredients together and that's all? As Kitchenelf suggested, this way sugar will not be dissolved sufficiently. One thing I can suggest is to use powdered sugar for a smoother texture.
