Potatoes on the half-shell
Bake large, smooth potatoes of uniform size until they yield to the pinching fingers. Divide each carefully in half, lengthwise; scrape out the interior, taking care not to break the skin; mash the potato with a little hot milk and melted butter until you can beat it to a cream; salt and pepper, beat in two tablespoonfuls of grated cheese (Parmesan is best) for two cupfuls of potato, and return to the waiting shells. Set in the oven until hot through and slightly browned. Serve in the skins.
They are very good.
