Take four ounces of boiled rice. Add to it pepper and salt to taste, a lump of butter about the size of a big Brazil nut, and two dessertspoonfuls of finely-grated cheese. Put this mixture into a well-greased bag, and make very hot for six minutes. Then open the bag and stir in gently two dozen picked shrimps. Mix in lightly with a fork. Replace the bag on the grid, and make hot for another three minutes. Dish up and serve. (350 Fahr.).
