Sauce Périgeux.—Fry in butter till lightly coloured 4oz. minced lean ham, two small shallots, the trim-mings of four or five truffles, and a pinch of black pepper; moisten it then with half a gill of Madeira or sherry, and reduce this rapidly to half. Pour on to this half a pint of rich espagnole, and half a gill of strong veal stock, and simmer it at the side of the stove for twenty minutes, skimming it carefully; then tammy, and again reduce till it will mask the spoon. Before serving, stir in a spoonful or two of finely sliced truffles cooked in a little sherry.
