In a bowl, combine together flour, salt, honey, preferment and melted butter.
Bring everything together to make soft slightly sticky dough with milk. Adjust milk quantity as needed.
Knead the dough for ten minutes on your counter or in a stand mixer.
Cover and set aside until double in volume.
Remove the dough from the bowl, gently de gas it and divide it into four equal portions.
Roll each portion tightly into a smooth roll, place on a baking tray, cover and set aside until 1.5 times the volume.
Preheat oven to 200C.
Brush the top of the rolls with milk and bake the buns in the preheated oven for 20 minutes.
Remove from oven, arrange on wire rack and let them cool completely.
