TO RENDER FAT BY COLD WATER METHOD
Cut fat in small pieces. Cover with cold water. Heat slowly. Let cook until bubbling ceases. Press fat during heating so as to obtain all the oil possible. When boiling ceases strain through cheesecloth and let harden. If desired one-half teaspoon salt, one-eighth teaspoon pepper, 1 teaspoon onion and 1 teaspoon poultry seasoning may be added before straining.
TO RENDER STRONG FLAVORED FATS
To mutton, duck or goose fat add equal amount of beef suet or vegetable fat and render same as suet. This may then be used for shortening, or pan broiling for meat or fish dishes, and not have the characteristic taste of the stronger fats.
When rendering strong mutton, duck or goose fats if a small whole onion is added the strong flavor of the fat is reduced. Remove the onion before straining. It may be used in cooking.
TO CLARIFY FAT
Melt the fat in an equal volume of water and heat for a short time at a moderate temperature. Stir occasionally. Cool and remove the layer of fat which forms on the top, scraping off any bits of meat or other material which may adhere to the other side.
Fats which have formed on top of soups, of cooked meats (such as pot roast, stews), salt meats (such as corned beef, ham, etc.), or strong fats, such as from boiled mutton, poultry and game, may be clarified in this way and used alone or combined with other animal or vegetable fats in any savory dish.
CARE OF FAT AFTER BEING USED FOR COOKING
If fat is used for deep fat frying as croquettes, doughnuts, fritters, etc., while fat is still hot, add a few slices raw potato and allow it to stay in the fat until it is cool. Remove potato—strain fat, allow to harden and it is ready to use. The potato absorbs odors from fat.
