Pour off through the spout of the roaster or tin-kitchen, all the fat from the top of the gravy, after you have done basting the meat with it. Hold a little sieve under the spout, and strain the dripping through it into a pan. Set it away in a cool place; and next day when it is cold and congealed, turn the cake of fat, and scrape with a knife the sediment from the bottom. Pat the dripping into a jar; cover it tightly, and set it away in the refrigerator, or in the coldest place you have. It will be found useful for frying, and for many other purposes.
Mutton-dripping cannot be used for any sort of cooking, as it communicates to every thing the taste of tallow.
