Baked Pawpaw

• 1 green (unripe) papaya, weighing about 3 lb.
• 2 oz. unsalted butter

Cut the unpeeled papaya in half, lengthwise. Scoop out and discard the seeds. Drop the fruit into boiling salted water and cook until tender, 15 to 20 minutes. Lift out and drain. Carefully scoop out the flesh, reserving the shells. Heat 1 oz. butter in a frying pan and sauté the onion until tender but not browned. Add the tomatoes, salt and pepper to taste and the papaya mashed. Mix thoroughly
