Combine warm water, sugar, and yeast in a bowl; let sit for 5 minutes.

Add melted butter and salt to the yeast mixture.

Gradually add flour, mixing until a soft dough forms.

Knead the dough on a floured surface for about 10 minutes.

Place the dough in a greased bowl, cover, and let it rise for 1 hour.

Punch down the dough and divide it into 12 pieces.

Shape each piece into a round ball and place on a baking tray.

Cover the rolls and let them rise for another 30 minutes.

Preheat the oven to 200°C (400°F).

Brush the rolls with melted butter, sprinkle with sesame seeds, and bake for 20-25 minutes.
