“ In making broth or soup, if the meat is covered with cold water instead of hot, more of the extractives will be drawn out and the broth will be more highly flavored and much more stimulating. The color, odor, and freshness of the muscular and fatty tissues of meat are all indicative of their quality. Fresh meat is firm in texture and free from offensive odor. Stale beef and that cut from an old steer exhales a pungent odor of butyric acid. The color of beef should be dark purplish when fresh cut but this changes quickly to a bright red ”
