Stewed Mushrooms.
Choose button mushrooms of uniform size. Wipe clean and white with a wet flannel cloth, and cut off the stalks. Put into a porcelain saucepan, cover with cold water, and stew very gently fifteen minutes. Salt to taste; add a tablespoonful of butter, divided into bits and rolled in flour. Boil three or four minutes; stir in three or four tablespoonfuls of cream whipped up with an egg, stir two minutes without letting it boil, and serve.
Or,
Rub them white, stew in water ten minutes; strain partially, and cover with as much warm milk as you have poured off water; stew five minutes in this; salt and pepper, and add some veal or chicken gravy, or drawn butter. Thicken with a little flour wet in cold milk, and a beaten egg.
