ONION SAUCE, Brown.
Ingredients.—6 large onions, rather more than ½ pint of good gravy, 2 oz. of butter, salt and pepper to taste. Mode.—Slice and fry the onions of a pale brown in a stewpan, with the above quantity of butter, keeping them well stirred, that they do not get black. When a nice colour, pour over the gravy, and let them simmer gently until tender. Now skim off every particle of fat, add the seasoning, and rub the whole through a tammy or sieve; put it back into the saucepan to warm, and when it boils, serve. Time.—Altogether 1 hour. Seasonable from August to March.
Note.—Where a high flavouring is liked, add 1 tablespoonful of mushroom ketchup, or a small quantity of port wine.
