Recipe: Leg of Mutton ala Venson

Remove all the rough fat from the MUTTON and lay it in a deep earthen dish; rub into it thoroughly the following: One tablespoonful of salt, one each of celery-salt, brown sugar, black pepper, English mustard, allspice, and some sweet herbs, all powdered and mixed; after which pour over it slowly a teacup of good vinegar, cover tightly, and set in a cool place four or five days, turning it and basting often with the liquid each day. To cook, put in a kettle a quart of boiling water, place over it an inverted shallow pan, and on it lay the meat just as removed from the pickle; cover the kettle tightly and stew for four hours. Do not lat the water touch the meat. Add a cup of hot water to the pickle remaining and baste with it. When done, thicken the liquid with flour and strain through a fine sieve, to serve with the meat; also a relish of currant jelly, the dame as for VENISON.
This is a fine dish when the directions are faithfully followed.
