Prepare a pair of sweetbreads by parboiling and skinning (see last recipe), then lard them all over the top; lay some slices of fat pork in a stewpan, also a teaspoon-ful of chopped onion, two of carrot, a stick of celery, and two sprigs of parsley; the vegetables must be finely minced; lay the sweetbreads on these; add a cup of stock, but not enough to cover the sweetbreads; let them slowly stew one hour; then take up the sweetbreads and set them with the larded side up in the oven till they are pale brawn; strain the gravy, rubbing as much through the sieve as you can; put it back in a saucepan, thicken with a teaspoonful of roux; put in a dozen and a half of canned mushrooms; let it boil a minute; put the sweetbreads on a dish, pour the mushrooms in the centre and the gravy round. If the stock should have dried away, boiling water or more stock can be added.
Parboil and skin them; cut them up in small pieces; put a tablespoonful of butter in a saucepan; when hot, drop the sweetbreads in with a saltspoonful of salt; let them cook slowly twenty minutes, occasionally shaking them; take them out; stir a teaspoonful of flour into the butter, and add half a cup of broth or water, stirring carefully; boil till thick and smooth; return the sweetbread; let it stew a minute, and serve either on squares of toast or with three-cornered pieces of toast sticking round it.
