Hard boil four eggs. Let them cool in a bowl of cold water. Peel them and divide them in half. Take the yolks and mix with them 1 heaping tablespoon of butter, Parmesan cheese grated, and a little salt and pepper. Put this mixture into a saucepan with the yolks of the raw eggs, and the white of one egg. Stir well until the mixture becomes thick. Then fill the hard-boiled whites of the eggs with the stuffing; if any stuffing remains over, spread it on the platter under the eggs. Then put milk in a saucepan with 1/2 tablespoon of butter and tablespoon of flour, salt, and pepper. Boil for a few moments, stirring well, then pour over the eggs, sprinkle well with grated Parmesan cheese, and put in the oven and brown.
