Mix dry yeast with sugar, warm water, warm milk and oil.

Leave for several minutes until foam forms. Whisk in egg and salt, sift in flour.

Knead the dough for about 10 minutes. Divide dough into eight equal pieces and shape into balls (don't worry, the dough should be quite sticky). Place on a sheet pan lined with parchment paper.

Spray some plastic wrap with non-stick cooking spray and place over the shaped buns. Place in a warm place for about an hour until buns double in size.

Whisk the egg white with water and brush buns with prepared egg wash. Sprinkle with seeds.

Preheat oven to 210 degrees C, bake for about 12 minutes until golden brown.
