Cut fish up in small pieces. Boil eggs hard and chop up. Take rice and boil in the following manner: After washing it well and putting it on in boiling water, with a little salt, let it boil for ten minutes, drain it almost dry and let it steam with the lid closely shut for ten minutes longer without stirring. Take a clean pot and put in the fish, eggs, rice, butter, and pepper and salt to taste. Stir over the fire until quite hot. Press into a mould and turn it out at once and serve.
