Cut the tomatoes in halves; place them in a frying-pan, the open side down, in one half inch deep of hot fat. Move them about until they are cooked a little tender. Then lift them carefully without breaking, and place them side by side in a baking-dish. Pour a little sweet oil around them; sprinkle with chopped garlic, and parsley, salt, pepper, and cayenne. Bake in hot oven fifteen to twenty minutes. Serve in same dish.
