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.
