Never had one, but I think someone was asking about them a few months ago. Here is a recipe that was in the local paper. Some of the amount are in teacups, which is 3/4 cup.
1 quart flour
1 teacup butter
2 teacups sugar
1 egg
1 teacup sour cream
1 tsp baking soda
1 tsp baking powder
2 tsp vanilla
1 tsp nutmeg
Cream butter and sugar. Add egg and beat well, stir in sour cream and vanilla. Mix dry ingredients, add a cup at a time. Beat only enough to incorporate flour. Dough will be sticky. Roll out a little more than 1/4 " thick. Cut with floured cutter. Bake on oiled pan at 350 degrees about 8-10 minutes, until slightly browned.
