Butter small timbale molds or custard cups, dust the bottoms and sides with chopped tongue and finely chopped mushrooms. Break into each mold one fresh egg. Stand the mold in a baking pan half filled with boiling water, and cook in the oven, until the eggs are "set." Have ready nicely toasted rounds of bread, one for each cup, and a well-made tomato or cream sauce. Loosen the eggs from the cups with a knife, turn each out onto a round of toast, arrange neatly on a heated platter, fill the bottom of the platter with cream or tomato sauce, garnish the dish with nicely seasoned green peas and serve at once.
