1 cup seedless raisins, ground
Frosting:
2 cups firmly packed brown sugar
½ cup evaporated milk
½ cup margarine
1 teaspoon vanilla extract
1 cup nuts
Preheat oven to 350 degrees. Cream margarine and beat in sugar until light and smooth. Add eggs, beating well. Combine flour, baking soda, and salt; add to creamed mixture alternately with sour mild or buttermilk. Add oranges and raisins, mixing well.
