Take a fireproof dish, and after sprinkling it with breadcrumbs put in it a layer of roast veal in slices, a layer of mashed potatoes, a layer of veal kidney, partly cooked, and cut into pieces and lastly a layer of potato. Cover the whole with a bechamel sauce into which you have stirred some grated cheese; put it to bake in the oven. Then make a brown sauce with any veal or kidney gravy that you have, and cook some mushrooms in it with pepper and salt; the sauce is to be served with the grenadine.
