STEWED MUSHROOMS

Having peeled and washed your mushrooms, drain them, and stew them with butter, pepper, salt, and a little chopped parsley, adding a little flour and warm water. When they are done, stir into the sauce the yolks of two or three eggs, and some cream. Toast and butter a slice of bread. Lay it on the dish under the mushrooms, and pour the sauce over them.

Put in a small onion with the mushrooms, that you may know by its turning almost black, whether there is a poisonous one among them. If the onion turns black, throw away all the mushrooms.
