1 1/4 c. sugar
1/2 c. butter
3 egg yolks
1/2 tsp. salt
1 c. sour cream
1 c. buttermilk
4 c. flour (maybe a little more)
3 good tsp. baking powder
1 good tsp. baking soda

By good, Grandma meant slightly rounded.

Mix together sugar, butter, egg yolks, sour cream and buttermilk. Spoon flour into measuring cup to measure. Add dry ingredients. Chill. Form into shape and bake at 425 to 450 degrees for about 6 to 8 minutes until slightly golden brown.

Aunt Berns she was throwing her recipe away and using this one.
