Take beef suet, the part around the kidneys, or any kind of fat, raw or cooked; remove as much as possible fibres, nerves, thin skin, or bones; chop it fine, put it in a cast-iron or crockery kettle; add to it the fat you may have skimmed from the top of broth, sauces or, gravies. Set the pan on a moderate fire; boil gently for about fifteen minutes, skim it well during the process; take from the fire, let it stand about five minutes, and then strain.
Put it in a stone jar or pot, and keep it in a dry and cool place. Cover the jar when perfectly cold.
It is as good as lard and more handy; it does not fly over the pan like lard.
A careful cook seldom buys fat; generally there is enough coming from skimming of broth, sauces, and gravies, for every purpose.
