1 tbsp. white vinegar
1 c. milk
2 c. unsifted flour
3 tbsp. sugar
1 tsp. salt
1/2 tsp. baking soda
1/3 c. shortening
1/2 c. seedless raisins
1 egg yolk, beaten
Sugar

Stir vinegar into milk and set aside. Combine flour, 3 tablespoons sugar, salt and baking soda in a bowl; stir well to blend. Cut in shortening until mixture resembles coarse crumbs. Stir in raisins. Add milk mixture to dry ingredients all at once and stir until all ingredients are moistened.

Turn out mixture onto a heavily floured board (about another 1/4 cup flour) and knead gently about 20 times. Place dough on an ungreased cookie sheet. Pat out to a 1/2 inch thick circle. Cut into 8 wedges, but do not separate. Brush with egg yolk and sprinkle with sugar. Bake in preheated 450 degree oven for 12 to 15 minutes or until done.
