While the dough is standing, cover the baking sheet with baking paper, oiling it. The dough increased in size. Again, with oiled hands, we crumple it and tear off a piece, forming buns. I have a small oven for 18 liters. The baking tray is small and it will fit 6 buns, located at a distance from each other. Separate the yolk from the egg and brush the top of the rolls, sprinkle with sesame. Put again on proofing for 15 minutes. Buns will increase in size. Since I put the buns on the rise in a warm oven, I do not take them out, immediately start baking, setting the t-180 C and time 20 minutes. That’s enough time for me. Focus on your oven. The buns will rise and grow before your eyes.
