=With Hydrochloric Acid.= Hydrochloric acid acts upon the fibers of meat in such a way that they become more easy of digestion. From a given portion of meat much more nutriment is extracted by the use of hydrochloric acid than without it; beef-tea made with it is recommended by physicians as the most easily absorbed form of beef drink, and for feeble children and patients much weakened by sickness it is especially useful. =To Prepare.= Select a half pound of good beef; remove from it everything that is not clear meat,--that is, bone, gristle, connective tissue, and fat; chop it fine on a meat-board or in a chopping-tray. Put into a bowl one cup of water and five drops of dilute hydrochloric acid; stir into this the chopped meat, and set it in a refrigerator or any cool place for two hours to digest. Then strain, flavor with salt, and serve cold in a red wine-glass. Should there be any objection to the taste or color, heat the tea until it steams and changes to a brownish hue; do not strain out the flakes of coagulated albumen and fibrin which appear, for they are the most nutritious portion of the tea. Chemically pure hydrochloric acid may be obtained of a druggist (it is usually marked C. P.); from it a diluted solution may be made by mixing it in the proportion of five and one half fluid ounces to fourteen ounces of water. BEEF BROTH Beef broth is the juice of beef extracted by the long application of heat in connection with some solvent, usually water. To make beef broth, allow one pound of meat, or meat and bone, to every quart of water. Wash the meat with a cloth in cold water until it is clean, or wipe it with a wet cloth if it is apparently fresh cut; divide it into small pieces (half-inch cubes) in order to expose as great an extent of surface as possible to the dissolving action of the water. Put it into a granite-ware kettle with _cold_ water, and cook it at a low temperature for two hours, then boil it for two hours to dissolve the gelatin. Remove it from the fire, and strain it, using a strainer so coarse that the flakes of albumen may go through (an ordinary wire strainer will do). Skim as much fat as possible from the surface with a spoon, and then remove the remaining small particles with a sheet of clean paper (unsized is best) drawn over the surface. Season the broth with salt and pepper, and serve it very hot. If not needed at once, it may be set away to cool, when the fat will rise to the top, and form into a cake which may be lifted off. =With Herbs.= Make a broth according to the above rule, and flavor it with bay-leaves, mint, or with a bouquet of sweet herbs in the proportion of one teaspoon to a quart of liquid.
