Wipe two slices chicken halibut, each weighing three-fourths pound. Cut one piece in eight fillets, sprinkle with salt and lemon juice, roll and fasten with small wooden skewers. Cook over boiling water. Cut remaining slice in pieces about the size and shape of scallops. Dip in crumbs, egg, and crumbs, and fry in deep fat. Arrange a steamed fillet in centre of each fish-plate, place on top of each a cooked mushroom cap, and put fried fish at both right and left of fillet. Serve with Mushroom Sauce, and garnish with watercress and radishes cut in fancy shapes.
Mushroom Sauce. Melt three tablespoons butter, add three tablespoons flour, and pour on gradually, while stirring constantly, one cup Fish Stock. When boiling-point is reached, add one-half cup cream, three mushroom caps, sliced, and one tablespoon Sauterne. Season with salt and pepper. The Fish Stock should be made from skin and bones of halibut. The mushroom caps on fillets should be cooked in sauce until soft.
