_To bake._--When prepared as directed above, put it in a baking-pan; spread a little butter over, put a little water in the bakepan and set in a quick oven, baste and turn over two or three times, and when done, serve with the gravy and the same sauces as if it were roasted.
_In Gratin._--Soak, drain and wipe it dry as directed.
Cut it in slices and put them in a crockery or other pan; turn a white sauce all over, then sprinkle on half a gill of vinegar or the juice of a lemon, dust with bread-crumbs, put half a dozen lumps of butter, each about the size of a hazelnut, all over; bake in a rather quick oven.
_Sauté._--When prepared as directed below, cut it in pieces as directed for kidney in _brochettes_. Then put a piece of butter the size of half an egg in a frying-pan and set it on the fire; when melted, sprinkle in a teaspoonful of flour, stirring with a wooden spoon the while, add half a wine-glass of white wine, a tablespoonful of broth, a pinch of chopped parsley, salt and pepper, boil ten minutes and lay the fillets in; have a quick fire, and as soon as cooked dish them, spread the sauce over, sprinkle on a few drops of lemon-juice, and serve.
_To prepare._--Never cook a kidney except it be very fresh. Prepare in the following way, a beef, sheep, or calf's kidney. Pig's kidneys are excellent if they have no disagreeable taste, but it is very often the case. The bad taste may be partly taken away by blanching the kidney, but it makes it tough and tasteless; it is better to throw it away.
_In Brochettes._--Split the kidney in four lengthwise, and then cut it in rather small pieces. Cut fat salt pork in pieces of the same size as the pieces of kidney--the fatty part of the kidney must not be used--then salt and pepper the pieces of kidney; take a common skewer and run it through a piece of kidney, then through a piece of salt pork; repeat this till the skewer is full. Fill as many skewers as are necessary till the whole kidney is used; and then roast before a good fire, basting often with melted butter. Serve warm.
_Another way._--Prepare as above, and instead of roasting, put the skewers in a bake-pan, spread a little butter over the kidney and salt pork, cover the bottom of the pan only with cold water, and bake. While in the oven, turn over and baste occasionally.
