Take three pounds of lean beef, salt it twelve hours with half a pound of common salt, and half an ounce of saltpetre; divide it into pound pieces, and put it into an earthen pan, that will just hold it; pour in half a pint of water; cover it close with paste, and set it in a very slow oven for four hours; when it comes from the oven, pour the gravy from it into a basin, shred the meat fine, moisten it with the gravy poured from the meat, and pound it thoroughly in a marble mortar with fresh butter, till it is as fine a paste as possible, season it with black pepper and allspice, or cloves pounded, or grated nutmeg; put it in pots, press it down as close as possible; put a weight on it, and let it stand all night; next day, when it is quite cold, cover it a quarter of an inch thick with clarified butter, and tie it over with paper. POTTED HAM. Cut a pound of the lean of boiled ham into pieces, pound it in a mortar with fresh butter, in the proportion of about two ounces to a pound of the ham, till it is a fine paste, season it by degrees with pounded mace, pepper, and allspice; put it close down in pots, and cover it with clarified butter a quarter of an inch thick; let it stand one night in a cool place, and tie it over with paper. Veal may be potted in a similar manner. POTTED LOBSTER. Take the meat and eggs from the shell; season it with powdered mace, cloves, nutmeg, pepper, salt, and anchovy liquor. Pound the meat in a marble mortar, and reduce the liquor, by evaporation, to a thick jelly; then put it and the meat together, with about one quarter of its weight of butter. Mix all together, and press it into a small pot; cover it with melted butter. When it is cold, put paper over the pots, and set them in a dry place. Craw fish, crabs, shrimps, and prawns, may be potted in the same way. PRESERVATION OF EGGS. Eggs may be kept for three or four months, or more, if the pores of the shell be closed, and rendered impervious to air by some unctuous application. We generally anoint them with mutton-suet, melted, and set them on end, wedged close together, in bran, _stratum super stratum_, the containing box being closely covered. Another method of preserving eggs is, to place them into a vessel containing lime water, or more properly slacked quicklime diluted with water, to the consistence of a thin cream, taking care that the eggs are completely covered with this liquid. The first mentioned process is, however, preferable, and answers exceedingly well. PRESERVATIVE EFFECT OF FROST, ON BUTCHER’S MEAT, FISH, AND FOWL. The preservative effect of frost on dead animal matter are of the utmost importance to the northern nations, by enabling them to store up a sufficient stock of all manner of animal provisions for their winter supply, and to receive stores from a great distance.
