1 1/2 c. Crisco shortening
2 lb. sifted confectioners' sugar
1/2 c. water
1-1 1/2 tsp. clear vanilla or desired flavoring

Cream shortening, sift sugar over the shortening, add scant 1/2 cup of water and flavoring. Mix on low speed to prevent air bubbles from forming. Cover bowl with damp towel and use as desired. This is my own personal recipe and I have found it enough to ice and decorate an average 1 mix size cake.
