Celery Sauce Purée, for boiled Turkey, Veal, Fowls, &c. (No. 290.)
Cut small half a dozen heads of nice white celery that is quite clean, and two onions sliced; put in a two-quart stew-pan, with a small lump of butter; sweat them over a slow fire till quite tender, then put in two spoonfuls of flour, half a pint of water (or beef or veal broth), salt and pepper, and a little cream or milk; boil it a quarter of an hour, and pass through a fine hair-sieve with the back of a spoon.
If you wish for celery sauce when celery is not in season, a quarter of a drachm of celery-seed, or a little essence of celery (No. 409), will impregnate half a pint of sauce with a sufficient portion of the flavour of the vegetable.
