Mushroom Sauce.
Mix a little flour with a good piece of butter; boil it up in some cream, shaking the saucepan; then throw in some mushrooms with a little salt and nutmeg: boil this up; or, if you like it better, put the mushrooms in butter melted with a little veal gravy, some salt, and grated nutmeg.
Sauce for roasted Mutton.
Wash an anchovy clean; put to it a glass of red wine, some gravy, a shalot cut small, and a little lemon-juice. Stew these together; strain them, and mix the liquor with the gravy that runs from the mutton.
Onion Sauce.
Let the onions be peeled; boil them in milk and water, and put a turnip into the pot; change the water twice: pulp them through a colander, or chop them as you please; then put them into a saucepan, with butter, cream, a little flour, and some pepper and salt.
Brown Onion Sauce.
Peel and slice the onions, to which put an equal quantity of cucumber or celery, with an ounce of butter, and set them on a slow fire; turn the onions till they are highly browned; stir in half an ounce of flour; add a little broth, pepper, and salt; boil it up for a few minutes; add a spoonful of claret or port, and some mushroom ketchup. You may sharpen it with a little lemon-juice. Rub through a tamis.
Oyster Sauce. No. 1.
Take two score of oysters, put them, with their own liquor, a few peppercorns, and a blade of mace, into a saucepan, and let them simmer a little over the fire, just to plump them; then with a fork shake each in the liquor so as to take off all the grit; strain the liquor, add to it a little good gravy and two anchovies, and thicken it with flour and butter, nearly as thick as custard.
