MEXICAN WEDDING COOKIES from the kitchen of Georgina Anderson

This is the recipe my grandmother used to make cookies for my wedding...

1 cup butter
1 tsp. vanilla
1/4 tsp. salt
1/2 cup icing sugar (powdered sugar)
2 cups flour

Cream together. Blend in flour. Chill 30 minutes or until it can be handled. Make 1" balls. Bake 1" apart on a cookie sheet at 375 degrees for 12-15 minutes. While warm, roll in powered sugar. Cool.
