Chop the chicken very fine, using the white meat alone, or the dark meat alone, or both together. Season with salt, pepper, onion-juice, and lemon-juice. Chopped mushrooms, sweetbreads, calf's brains, tongue, or truffles are used with chicken, and a combination of two or more of them much improves the quality of the croquettes.
CROQUETTES OF CALF'S BRAINS
Lay the brains in salt water an hour, or until they look perfectly white, then take out one at a time, pat with your hands to loosen the outer skin and pull it off. Beat or rub them to a smooth paste with a wooden spoon, season with salt and pepper and a very little mace; add a beaten egg and about one-half cup of bread crumbs. Heat fat in a spider and fry large spoonfuls of this mixture in it.
MEAT CROQUETTES
Veal, mutton, lamb, beef and turkey croquettes may be prepared in the same way as chicken croquettes.
MEAT AND BOILED HOMINY CROQUETTES
Equal proportions.
SWEETBREAD CROQUETTES
Cut the boiled sweetbreads into small dice with a silver knife. Mix with mushrooms, using half the quantity of mushrooms that you have of sweetbreads. Use two eggs in the sauce.
