Open and blanch for five minutes twenty-four medium-sized oysters in a sautoire with half a glassful of white wine and half an ounce of butter. Season with half a pinch of pepper and a third of a pinch of nutmeg. Let cook for five minutes; then add one pint of well-reduced veloute sauce (No. 152), and let cook for another five minutes, adding half an ounce of crawfish butter (No. 150), and stirring it occasionally. Fill six buttered paper boxes with four oysters each, and the garnishing equally divided. Sprinkle over a little fresh bread-crumbs, and arrange them on a tin roasting-pan. Spread a very little butter over each patty, and put them in a moderate oven for five minutes. Have a hot dish ready, with a folded napkin nicely arranged on it; dress the patties over, and serve.
