Preparation

• In a large bowl, combine the warm milk, yeast, and sugar. Let it sit for about 5-10 minutes until foamy.
• Stir in the melted butter and the egg. Mix well.
• In a separate bowl, whisk together the flour and salt.
• Gradually add the dry ingredients to the wet ingredients, mixing until a shaggy dough forms.
• Turn the dough out onto a lightly floured surface and knead for 8-10 minutes until smooth and elastic.
• Place the dough in a lightly oiled bowl, cover with plastic wrap, and let it rise in a warm place for 1-1.5 hours, or until doubled in size.
• Punch down the dough and divide it into 8 equal pieces. Shape each piece into a ball.
• Place the dough balls on a baking sheet lined with parchment paper, leaving space between them. Flatten them slightly with your palm.
• Cover the buns and let them rise for another 30-45 minutes.
• Preheat oven to 190.0°C (375.0°F).
• Whisk together the egg yolk and water for the egg wash. Brush the tops of the buns with the egg wash.
• Bake for 15-18 minutes, or until golden brown.
• Let the buns cool on a wire rack before slicing and serving.
