Activate the yeast

• Combine the yeast, sugar, warm water and warm milk in a bowl.
• Let the mixture sit until foamy.

Make the dough

• Add the egg white, salt and flour, then mix into a soft, sticky dough.
• Knead for 15 minutes until the gluten is developed and the dough is elastic.
• Add the butter and knead until fully absorbed and smooth.

Rest the dough

• Cover the dough and let it relax to make shaping easier.
• Grease your hands with oil instead of adding flour if the dough is sticky.

Shape and proof

• Shape the dough into a smooth loaf and place it in a greased loaf pan.
• Cover and let it rise until doubled in size.

Brush and bake

• Preheat the oven to 190 °C.
• Brush the loaf with the egg yolk mixed with milk and sprinkle with sesame seeds if desired.
• Bake until golden brown.

Cool

• Cover the bread with a clean towel right after baking to keep it soft.
• Let it cool before slicing.
