Prepare them the same as for stewing. Place them in a baking-pan in a moderate oven. Season with salt, pepper, lemon juice and chopped parsley. Cook in the oven fifteen minutes, baste with butter. Arrange on a dish and pour the gravy over them. Serve with sauce made by heating a cup of cream, two ounces of butter, a table-spoonful of chopped parsley, a little cayenne pepper, salt, a table-spoonful of white sauce and two tablespoonfuls of lemon juice. Put in a saucepan and set on the fire. Stir until thick, but do not let boil. Mushrooms are very nice placed on slices of well-buttered toast when set into the oven to bake. They cook in about fifteen minutes
Time, twenty-one minutes. Button mushrooms, salt to taste, a little butter rolled in flour, two tablespoonfuls of cream or the yolk of one egg. Choose buttons of uniform size. Wipe them clean and white with a wet flannel; put them in a stewpan with a little water and let them stew very gently for a quarter of an hour. Add salt to taste, work in a little flour and butter, to make the liquor about as thick as cream, and let it boil for five minutes. When you are ready to dish it up, stir in two tablespoonfuls of cream or the yolk of an egg; stir it over the fire for a minute, but do not let it boil, and serve. Stewed button mushrooms are very nice, either in fish stews or ragouts, or served apart to eat with fish. Another way of doing them is to stew them in milk and water (after they are rubbed white), add to them a little veal gravy, mace and salt and thicken the gravy with cream or the yolks of eggs.
Canned mushrooms may be served with good effect with game and even with beefsteak if prepared in this way: Open the can and pour off every drop of the liquid found there; let the mushrooms drain, then put them in a saucepan with a little cream and butter, pepper and salt; let them simmer gently for from five to ten minutes, and when the meat is on the platter pour the mushrooms over it. If served with steak, that should be very tender and be broiled, never in any case fried.
Wash and wipe free from grit the small fresh button mushrooms. Put into a frying pan a quarter of a pound of the very best butter.
Add to it two whole cloves, a saltspoonful of salt and a tablespoonful of lemon juice. When hot add a quart of the small mushrooms, toss them about in the butter for a moment only, then put them in jars; fill the top of each jar with an inch or two of the butter and let it cool. Keep the jars in a cool place, and when the butter is quite firm add a top layer of salt. Cover to keep out dust.
The best mushrooms grow on uplands or in high open fields, where the air is pure.
