Step 1Soak the dried limas overnight in water to cover.
Step 2In the morning, pour off the liquid. Cover the beans with boiling water and boil 1/2 hour. Drain, reserving the water.
Step 3Heat the oven to 325 degrees. Grease a 9-inch square baking pan with bacon drippings.
Step 4Combine the sugar, mustard, salt and paprika. Make a layer of beans in the pan, then sprinkle with some of the seasonings. Make additional layers of beans and seasonings until they're all used up. Cover the beans with bacon slices. Pour the water in which the beans were boiled gently over the contents of the pan just to come even with the bacon slices.
Step 5Bake the beans until they're very tender, 1 1/2 to 2 hours.
