Combine flour, sugar, salt, and yeast in a bowl. Make a well in the center, add milk, oil, and egg white, and knead into a soft dough.

Cover the dough and let it proof for 1 hour.

Divide the dough into equal portions, flatten each piece, spread melted butter inside, roll it up, twist, and shape into rings.

Place the rings on a baking tray lined with parchment paper, brush with egg yolk, and sprinkle with sesame or black cumin seeds.

Bake in a preheated oven at 180°C (350°F) for 20 minutes until golden brown.
