I received this recipe from a coworker of mine more than 20 years ago. It's one of my family favorites.
3 1/4 cup sifted flour
1 tsp. soda
1 cup sugar
1 tsp. vanilla
1/2 tsp. salt
1/2 cup butter or crisco
1/2 cup sour cream
In a large bowl combine sugar, egg, vanilla, or crisco and sour cream.
Beat for two minutes.
Add flour and stir until well mixed.
Roll out 1/4 inch thick on lightly floured board. Cut into desired shapes. Place on buttered cookie sheet. Bake at 400 degrees for 8-10 minutes until done but not brown. Decorate with your choice of frosting, sugars and/or decorations. Makes about 2 1/2 dozen.
