Cut the stems closely from a quart or more, of small just-opened mushrooms; peel them, and take out the gills. Dissolve from two to three ounces of fresh butter in a well-tinned saucepan or stewpan, put in the mushrooms, strew over them a quarter of a teaspoonful of pounded mace mixed with a little cayenne, and let them stew over a gentle fire from ten to fifteen minutes; toss or stir them often during the time; then add a small dessertspoonful of flour, and shake the pan round until it is lightly browned. Next pour in, by slow degrees, half a pint of gravy or of good beef-broth; and when the mushrooms have stewed softly in this for a couple of minutes, throw in a little salt, and a squeeze of lemon-juice, and pour them on to a crust, cut about an inch and a quarter thick, from the under part of a moderate-sized loaf, and fried in good butter a light brown, after having been first slightly hollowed in the inside. New milk, or thin cream, may be used with very good effect instead of the gravy; but a few strips of lemon-rind, and a small portion of nutmeg and mushroom-catsup should then be added to the sauce. The bread may be buttered and grilled over a gentle fire instead of being fried, and is better so.
