If you have a steak that does not appear to be too tender, put it in a saucepan with a little piece of butter and some good olive oil, with a taste of garlic and bay-leaf or rosemary. Add, if necessary, a little broth or water or tomato sauce and serve with potatoes cooked in the gravy that can be made more abundant with more broth, butter and tomato sauce.
Take a veal kidney, remove the fat, cut it open and cover with boiling water. When the water has cooled, remove the kidney, wipe with a cloth, and pass through it clean sticks to make it stay open. Season with melted butter, salt and pepper and leave it so prepared for an hour or two.
Then take another piece of butter and two or three anchovies. Clean the latter, chop and mix with the butter with the blade of a knife, making a ball. Cook the kidney on the grill, but not too much, in order to keep it tender, put it on a plate and grease when hot with the ball of butter and anchovies.
Cut in thin slices one or two veal kidneys, removing the granulous part that is to be found in the middle, and put the slices in a saucepan with a piece of butter, a bunch of parsley chopped very fine together with a clove of garlic. Add a cup of hot broth; salt moderately and let it cook without boiling, until the sauce is reduced to about one third.
One tablespoonful of vinegar adds a pleasant taste to this dish.
After washing the kidneys, remove the filmy skin that covers them and cut them in the middle without, however, detaching completely the two parts. Season with salt and pepper, grease with oil and put them on a strong fire on the grill. After ten or twelve minutes they will be broiled. Serve hot with parsley and slices of lemon.
Wash, remove the skin that covers the kidneys and cut in very thin slices. Wipe with a cloth, dip first in ground bread crumbs, then in a beaten egg mixed with melted butter, then again in the bread crumbs. This must be done rapidly, at the time of frying, otherwise the bread crumbs absorb the moisture of the kidney and make them too hard.
Melt a piece of butter in a saucepan on a strong fire and when it begins to brown, dip the slices of kidney. Turn often, sprinkle with a little parsley chopped fine, salt and serve with lemon.
