Preheat oven to 350°F.

Grease a 9-10 inch cast iron skillet.

In a large bowl, mix together the flour, raisins, baking soda, salt, caraway seeds, sugar, and baking powder.

Using your fingers, quickly cut in the shortening.

Add the 2 cups buttermilk and stir until combined.

Shape the dough into a rough flattened ball and place on the cast iron skillet and bake for 40 to 45 minutes. Test for done-ness by up upending it on its side and thumping it in the middle — if it sounds hollow, it’s done.

Remove to a rack and cool.
