1 c. self rising flour
1/4 c. sugar
1 tsp. cinnamon
1/4 tsp. baking soda
1/3 c. shortening
1/2 cup raisins
3/4 to 1 cup buttermilk

Frosting:

3/4 c. powered sugar
2 to 3 tsp. milk

Heat oven to 450°F. Lightly spoon flour into measuring cup; level off. In large bowl, combine flour, sugar, cinnamon and baking soda. Using pastry blender or fork, cut in shortening until mixture resembles coarse crumbs; stir in raisins. Stirring with fork, add enough buttermilk until mixture leaves sides of bowl and soft dough forms. Turn dough on a floured surface; knead lightly until no longer sticky. Roll out until 1/2 inch thick; cut with floured biscuit cutter. Place on ungreased cookie sheet with sides touching.

Bake at 450°F for 10 to 15 minutes. Meanwhile mix powdered sugar and enough milk for desired frosting consistency. Frost warm biscuits and serve while warm.
