White Sauce, for boiled Fowls.
Have ready a sauce, made of one pint of veal jelly, half a quarter of a pound of butter, two small onions, and a bunch of parsley; then put three table-spoonfuls of flour, half a pint of boiling hot cream, the yolks of three eggs, a pinch of cayenne pepper, and the same of salt; boil all up together, till of a tolerable thickness; keep it hot, and take care that it does not curdle. Make ready some slices of truffles, about thirty-four, the size and thickness of a shilling, boil them in a little meat jelly; strain them, and add the truffles to the sauce previously made. When ready to serve, pour the sauce and truffles over whatever meat they are destined for.
