Sweetbreads a la Montebello

Blanch until firm to the touch some medium-sized sweetbreads that have been in soak for a few hours, then drain, refresh and pare by suppressing all the sinews and fat. Lay them in a sautoir lined with slices of fat pork, sliced onions and carrots and a bunch of parsley, moisten to half their height with beef-stock (No. 194a), let this liquid fall to a glaze and then remoisten; cover with a buttered paper and finish cooking in a slack oven. After they are done pare and set them in oval tin rings, two and a half by five-eighths of an inch in diameter and half an inch high; let them cool off in these under the pressure of a weight. Cut up the parings into small three-sixteenths inch dice; also some mushrooms and truffles; fry a chopped shallot in butter, add to it the mushrooms, the truffles and the sweetbreads, also a little veloute (No. 415), then season; when this preparation is cold, use it to cover one side of the sweetbreads, having it well rounded on the top, cover over with a layer of cream forcemeat (No. 75), and dredge the surface with finely chopped red tongue; place the sweetbreads on a buttered baking pan, pour melted butter over and the sweetbreads in a slack oven for twenty minutes; serve a Montebello sauce (No. 502) separately.
