When through frying, add a pared potato, cut in slices, to the fat, and let stand on back of range until potato has browned. Remove potato and strain fat through a cheese cloth. Fat clarified in this way may be used indefinitely.
Let melted butter stand in a dish on back of the range until the salt has settled, then pour off butter, leaving sediment in the bottom of the dish.
When fat is put on the range to heat for frying, put in a cube of bread. If the fat is forgotten, the bread will burn first, and the odor of the burned crumb will attract the attention. The burned flavor cannot be removed from burned fat.
Cut the suet in small pieces, place in top of double boiler, cover, and cook over hot water until all the fat is tried out; strain through a cheese cloth. This can be done in the oven if the top of the range is crowded.
Larding is accomplished by cutting strips of salt pork lengthwise with the rind two inches long and one quarter inch wide, and with aid of the larding needle drawing these pieces through the surface of the meat, taking a stitch an inch long and a quarter inch deep.
Heat the fat. When a blue smoke begins to appear, drop in a cube of bread; if the bread browns a golden brown in forty seconds, the fat is hot enough for any food which has previously been cooked. Uncooked food requires a longer, slower frying; the cube of bread should brown in sixty seconds for such food.
Food cooked in fat tested in this way should never soak fat if one is careful to put a small enough quantity of food in at a time - not enough to cool the fat.
For meat croquettes, cold cooked meat should be freed from skin and gristle, and cut quite fine, then mixed with a thick sauce to as soft a consistency as it is possible to handle. Chill before shaping. For vegetable croquettes the vegetables should be boiled, then mashed and seasoned. Chill before shaping.
Allow one rounding tablespoon of croquette mixture for each croquette, roll into a round ball, roll ball in crumbs, then shape either like a cylinder or pyramid; when all are perfect and uniform, dip in egg, then in crumbs.
Soak in cold water from the time they come from the market until used. Drain, cover with two cups cold water, add four cloves, one and a half teaspoons salt, two tablespoons vinegar or lemon juice, and a slice of onion; simmer for one half hour, drain, cover with cold water, remove tubes and membranes. Broil whole; or if for larding, dip in egg, wrap in cheese cloth, and press under weight over night.
Place sugar in clean agate-ware frying pan, and stir continually until the sugar becomes a golden brown sirup.
Place food to be poached in frying pan half filled with boiling salted water. Cook below the boiling point from three to eight minutes.
Place butter in bowl, and mash against the sides of the bowl, with a spoon, until of a creamy consistency.
Pour mixture into bowl, and cut through and through mixture with a spoon, then take up some of mixture in spoon, and turn spoon completely over, and fold under mixture. Continue this process until mixture is blended.
When frosting is nearly cold, cut with a silver knife, wiping knife after making each crease.
