Wash thoroughly several fowls' livers and then let them simmer until tender in a little strong soup stock, adding some sliced mushroom, minced onion, and a little pepper and salt. When thoroughly done mince the whole finely, or pound it in a mortar. Now put it back in the saucepan and mix well with the yolks of sufficient eggs to make the whole fairly moist. Warm over the fire, stirring frequently until the mixture is quite thick, taking care that it does not burn.
It should be served upon rounds of toast on a hot dish garnished with parsley.
