Peel and cut six onions in slices; put in a stewpan, with a quarter of a pound of butter, a teaspoonful of salt, one of sugar, a half one of pepper; place on a slow fire to simmer till in a pulp, stirring them now and then to prevent them getting brown, then add one tablespoonful of flour, a pint of milk, and boil till a proper thickness, which should be a little thicker than melted butter; pass through a sieve, warm again, and serve with mutton cutlets, chops, rabbits, or fowl; by not passing it, it will do for roast mutton and boiled rabbit as onion sauce.
