Professional Butter Cream Frosting

1 1/4 cups Crisco shortening (only use Crisco)
2 pounds confectioners' sugar
1 teaspoon salt
1/2 cup water
2 tablespoons Karo light corn syrup
1 teaspoon butter flavoring
1 teaspoon vanilla extract

Beat 5 to 10 minutes with an electric mixer until very smooth. Water down a small amount for a crumb coat if frosting a cake. After 20 minutes (when set), frost with remainder of frosting. When set, use paper towel or typing paper to set desired surface texture.

This is fluffy enough to frost easily, yet stiff enough for keeping its shape for decorating.
