Steam the pumpkin with the skin on, scoop out the flesh, and mash it.
Add bread flour, sugar, salt, yeast, milk, eggs, and butter to the mashed pumpkin and knead the dough.
Let the dough ferment for the first time.
Divide the dough into appropriate portions, shape them into balls, and place them on a pan.
After the second fermentation, brush milk on the surface.
Bake in a preheated oven at 180°C for 20 minutes.
