Cut and chop a knuckle of veal, weighing about four pounds, into large dice; also half a pound of lean bacon; butter the bottom of a large stewpan with a quarter of a pound of butter, add two onions, a small carrot, a turnip, three cloves, half a blade of mace, a bouquet of a bay-leaf, a sprig of thyme, and six of parsley, add a gill of water, place over a sharp fire, stirring round occasionally, until the bottom of the stewpan is covered with whitish glaze, when fill up with three quarts of water, add a good teaspoonful of salt, and let simmer at the corner of the fire an hour and a half, keeping well skimmed, when pass it through a hair sieve into a basin; in another stewpan put a quarter of a pound of butter, with which mix six ounces of flour, stirring over the fire about three minutes, take off, keep stirring until partly cold, when add the stock all at once, continually stirring and boiling for a quarter of an hour; add half a pint of boiling milk, stir a few minutes longer, add a little chopped mushrooms if handy, pass through a hair sieve into a basin, until required for use, stirring it round occasionally until cold; the above being a simplified white sauce, will be referred to very often in the receipts.
