Cut a pound of the lean of fresh juicy beef into small thin slices, and sprinkle them with a very little salt. Put the meat into a wide-mouthed glass or stone jar closely corked, and set it in a kettle or pan of water, which must be made to boil, and kept boiling hard round the jar for an hour or more. Then take out the jar and strain the essence of the beef into a bowl. Chicken tea may be made in the same manner.
