MATELOTE OF EELS À LA PARISIENNE

Clean and cut the eels into four-inch pieces. Cover with white wine and season with sliced carrot and chopped mushrooms. Add also the liquor from three dozen parboiled oysters. Simmer until the eels are done and drain. Add to the liquor half a cupful of white stock, and thicken with flour cooked in butter. Add two wineglassfuls of white wine and boil until thick, stirring constantly. Take from the fire, and add the yolks of four eggs beaten smooth with the juice of half a lemon, a tablespoonful of butter, and a grating of nutmeg. Add the parboiled oysters, and a handful of button mushrooms. Reheat, pour over the fish, and serve.
