Like Safeway' icing
125 ml (1/2 cup) shortening
500 ml (2 cups) icing sugar
pinch salt
2 ml (1/2 tsp) vanilla
up to 60 ml (1/4 cup) whipping cream
In a large bowl, beat shortening until fluffy. Using an electric mixer, add sugar gradually, beating well until mixture comes together. (This may take some time.) Add salt, vanilla and whipping cream to desired consistency, beating at low speed. Increase speed to high and whip until frosting is light and fluffy, 5-10 minutes. Makes enough icing for a 22x33 cm (9x13 in) cake.
