5 tbsp. flour
1 c. milk

Put above ingredients in a blender until completely mixed or mix with a whisk, but it must be completely blended. Put into a small pot and cook over low heat until the consistency of pudding. COVER AND COOL COMPLETELY. Set aside, then:

1/2 c. butter
1/2 c. Crisco shortening
1 c. granulated sugar
1 tsp. vanilla

Cream together 1/2 cup of shortening and 1/2 cup of butter until light and fluffy. To that add 1 cup granulated sugar a little at a time and beat until the sugar is dissolved. THIS MAY TAKE AS LONG AS TEN MINUTES - BE PATIENT. When dissolved or near to being dissolved, add the cooled flour mixture and beat until fluffy, then add vanilla.

NOTE: Other flavors may be substituted for the vanilla. Also, liquid chocolate or cocoa may be added. If you like color it takes food coloring beautifully.
