ONIONS AU GRATIN
Prepare as for creamed onions, making a white sauce of the milk, or milk and water, in which the onions have been boiled. The onions can be left whole, or somewhat broken up in the sauce. Fill a buttered baking dish with onions and sauce, dust the top with grated cheese, and let heat in the oven five or six minutes. The bottled Parmesan cheese is convenient, but is never as delicate to the taste as fresh cheese grated.
