Add a soupspoon of butter, 1/2 soup spoon of salt, 1 and 1/2 glasses of water. Cook on a low heat for 1 and 3/4 to 2 hours.

Remove the meat from the saucepan and put onto a plate. Roll each piece of meat in 2 eggplant slices, one at a right angle to the other. Fix the ends with toothpicks, if necessary. Place the wrapped pieces of meat in a large, deep frying pan. Clean the brain under running water. Remove the membrane and the small veins. Boil for 15 minutes in water. Cut into 6 pieces and place one on each piece of meat. Decorate the top with a tomato slice. Pour the sauce in which the meat was cooked into the frying pan. Cover and cook on a low heat for 1/2 hour.
