Now all of a sudden my frosting is grainy like. Am I mixing it too much? I have switched powdered sugars and sifted them. My recipe is 1/2 cup of crisco and 1/2 cup of butter and 4 cups of powdered sugar. It worked before. I dont know what happened!! Maybe I need to make one batch at a time instead of 2?
Is it the food coloring? It's a gel food coloring. I've never had an issue with too much food coloring or it affecting the frosting
