Take the chickens; skin them; take out the lungs and wash them thoroughly; put them in a stewpan with some parsley. Add a quart of veal jelly, and stew them in this for one hour over a very slow fire. Then take out the chickens, and put the penny roll to soak in the liquor; take all the flesh of the chickens from the bones, and pound it in a mortar, with the yolks. Add the bread (when soaked enough) and pound it also with them; then rub the whole finely through a sieve. Add a quart more jelly to the soup, and strain it through a sieve; then put the chicken to the soup. Set the cream on the fire till it boils, stirring it all the time; when ready to serve, pour that into the soup and mix it well together. Have ready a little vermicelli, boiled in a little weak broth, to throw into the soup, when put into the terrine.
