Pour milk into a saucepan and add butter. Cook on low heat until the butter melts. Set aside and cool it down (it should be lukewarm, but not hot).

Mix the flour with yeast, sugar and salt. Slowly pour milk with butter, and begin to knead the dough with a mixer. Add the eggs and continue kneading the dough. After 5 minutes, it will have the form of a ball.

Leave the dough in a bowl and cover it with a cloth. Leave in a warm place for an hour.

After doubling the volume, divide the dough into 8 portions. Flatten each ball and form the rolls.

Place the rolls on the baking tray lined with parchment paper. Cover them with a cloth and leave for 45 minutes. During this time, it should double in volume.

Cut the three lines on each roll with a sharp knife. Mix the beaten egg with a teaspoon of milk and grease the top of the rolls. Bake at 360 F for 15 minutes until lightly browned. Cool on the rack before serving.
