POTTED BEEF

642. INGREDIENTS.--2 lbs. of lean beef, 1 tablespoonful of water, 1/4 lb. of butter, a seasoning to taste of salt, cayenne, pounded mace, and black pepper.

_Mode_.--Procure a nice piece of lean beef, as free as possible from gristle, skin, &c., and put it into a jar (if at hand, one with a lid) with 1 tablespoonful of water. Cover it _closely_, and put the jar into a saucepan of boiling water, letting the water come within 2 inches of the top of the jar. Boil gently for 3-1/2 hours, then take the beef, chop it very small with a chopping-knife, and pound it thoroughly in a mortar. Mix with it by degrees all, or a portion, of the gravy that will have run from it, and a little clarified butter; add the seasoning, put it in small pots for use, and cover with a little butter just warmed and poured over. If much gravy is added to it, it will keep but a short time; on the contrary, if a large proportion of butter is used, it may be preserved for some time.

_Time_.--3-1/2 hours. _Average cost_, for this quantity, 1s. 8d.

_Seasonable_ at any time.

POTTED BEEF (Cold Meat Cookery).

643. INGREDIENTS.--The remains of cold roast or boiled beef, 1/4 lb. of butter, cayenne to taste, 2 blades of pounded mace.

_Mode_.--As we have stated in recipe No. 608, the outside slices of boiled beef may, with a little trouble, be converted into a very nice addition to the breakfast-table. Cut up the meat into small pieces and pound it well, with a little butter, in a mortar; add a seasoning of cayenne and mace, and be very particular that the latter ingredient is reduced to the finest powder. When all the ingredients are thoroughly mixed, put it into glass or earthen potting-pots, and pour on the top a coating of clarified butter.

_Seasonable_ at any time.

_Note_.--If cold roast beef is used, remove all pieces of gristle and dry outside pieces, as these do not pound well.

PRESERVED MEATS.--When an organic substance, like the flesh of animals, is heated to the boiling-point, it loses the property of passing into a state of fermentation and decay. Fresh animal milk, as is well known, coagulates, after having been kept for two or three days, into a gelatinous mass; but it may be preserved for an indefinite period, as a perfectly sweet liquid, if it be heated daily to the boiling-point. The knowledge of this effect of an elevated temperature has given rise to a most important branch of industry,--namely, the preparation of preserved meats for the use of the navy and merchant service. At Leith, in the neighbourhood of Edinburgh, at Aberdeen, at Bordeaux, at Marseilles, and in many parts of Germany, establishments of enormous magnitude exist, in which soup, vegetables, and viands of every description are prepared, in such a manner that they retain their freshness for years. The prepared aliments are inclosed in canisters of tinned iron plate, the covers are soldered air-tight, and the canisters exposed to the temperature of boiling water for three or four hours. The aliments thus acquire a stability, which one may almost say is eternal; and when a canister is opened, after the lapse of several years, its contents are found to be unaltered in taste, colour, and smell. We are indebted to the French philosopher Gay-Lussac for this beautiful practical application of the discovery that boiling checks fermentation. An exclusive salt-meat diet is extremely injurious to the health; and, in former times, thousands of mariners lost their lives for the want of fresh aliments during long voyages. We are sorry to say that the preserved meats are sometimes carelessly prepared, and, though the statement seems incredible, sometimes adulterated. Dr. Lankester, who has done so much to expose the frauds of trade, that he ought to be regarded as a public benefactor, says that he has seen things which were utterly unfit for food, shipped as preserved meats.
