Onion Sauce.

Peel the onions, boil tender, press the water from them, and mince fine. Have ready the hot milk in a saucepan; stir in the onions, then the butter, salt, and pepper. Boil up once.

If you want to have it particularly good, make nice melted or drawn butter (No. 3); beat the mashed onion into it; add a teacupful of cream or new milk, season, boil up, and serve.
