This is an old recipe from my MIL's recipe box. I have no other history on it. It's super cool, flavored with the orange and raisins being ground together. Enjoy!
3/4 cup sugar
1/2 cup shortening
1 cup sour milk
2 1/4 cup flour
1/2 tsp salt
1 tsp soda
1 cup raisins
In a mixing bowl, combine sugar and shortening until light and fluffy.
Add egg and combine thoroughly.
In a smaller mixing bowl, combine flour, salt and baking soda.
Alternate adding dry ingredients and sour milk to sugar mixture.
Grind orange and raisins together in a food processor until smooth. Add to batter.
Pour batter into a greased cake pan and bake at 350 degrees for 30 minutes, or until knife comes out clean when inserted into center of cake.
