After washing the heart thoroughly cut it up into squares half an inch long; put them into a Saucepan with water enough to cover them. If any scum rises skim it off. Now take out the meat, strain the liquor and put back the meat, also add a sliced onion, some parsley, a head of celery chopped fine, pepper and salt and a piece of butter. Stew until the meat is very tender. Stir up a tablespoonful of browned flour with a small quantity of water and thicken the whole. Boil up and serve.
