You must judge according to the largeness of your turkey or fowl, what celery or sauce you want. Take a large fowl, put it into a sauce-pan or pot, and put to it one quart of good broth or gravy, a bunch of celery washed clean and cut small, with some mace, cloves, pepper, and allspice tied loose in a muslin-rag; put in an onion and a sprig of thyme; let these stew softly till they are enough, then add a piece of butter rolled in flour; take up your fowl, and pour the sauce over it. An hour will do a large fowl, a small turkey; but a very large turkey will take two hours to do it softly. If it is overdone or dry it is spoiled; but you may be a judge of that, if you look at it now and then. Mind to take out the onion, thyme, and spice, before you send it to table.
Note, A neck of veal done this way is very good, and will take two hours doing.
