Purée of Mushrooms.—Wash and press the water from half a pound of fresh mushrooms, chop them fine and put them in a stewpan with one ounce of good butter, half a chopped eschalot, a pinch of finely-chopped parsley; season with salt and a little white pepper, and fry carefully for eight or ten minutes; then mix with half an ounce of chopped ham or tongue, and half an ounce of glaze; boil up, mix with one ounce of finely chopped cooked white meat, set aside to cool, and use.
