SAUCE A LA GASCONNE.
Take a small spoonful of French capers, with about an ounce of truffles, and chop each separately very fine; put these into a small stewpan, together with one clove of garlic, a tablespoonful of salad oil, some pepper, and nutmeg; fry them lightly on the stove-fire for two or three minutes; moisten with a glass of French white wine, set the whole to boil on the stove-fire for three minutes; then add a small ladleful of white Velouté sauce, a bay-leaf, and a sprig of thyme; stir the sauce on the fire till it boils, then set it by the side to continue boiling gently; skim it well, and after having added another glass of wine, reduce the sauce and thicken it with a lesson of three yolks; pour the sauce into a bain-marie, and just before using it mix in a spoonful of chopped and blanched chives, parsley, and tarragon, a pat of anchovy butter, and some lemon-juice.
