Apples and Sweet Potatoes

Peeled, sliced apples, and sweet potatoes (the potatoes are previously boiled, peeled and sliced), arranged in alternate rows, are very good served with roast loin of pork or chops. Butter a shallow casserole, and lay enough butter over the potatoes and apples to moisten the whole. Serve in the dish in which they were baked. Add sugar if the apples are very tart.
