Take six good-sized, firm, red, fresh tomatoes; pare the underparts in case anything adheres, wipe them nicely, and slit them in halves. Lay them on a dish; season with a good pinch of salt, half a pinch of pepper, and a tablespoonful of sweet oil; mix well together; keep the tomatoes in as good shape as when cut, then arrange them in a double broiler. Put them on a moderate fire, and cook for eight minutes on each side. Place in a hot dish; spread a gill of maitre d'hotel butter (No. 145) over them, and serve.
