Wipe well a two-pound piece of fresh halibut, lay it on a dish, and season it with a pinch of salt, a pinch of pepper, and two tablespoon-fuls of sweet oil. Roll it well and lay it on a double broiler; then place it on a brisk fire, and broil for eight minutes on each side. Dress the fish on a hot dish, pour a gill of maitre d'hotel sauce (No. 107) over, decorate with parsley-greens, and serve.
