Instructions
Read through once, then cook at your own pace with the illustrated guide above.
- 1
In a large mixing bowl, combine the flour, instant yeast, and salt. Mix well to combine the dry ingredients.
- 2
In another bowl, whisk together the warm whole milk, melted butter, 1/4 cup of sugar, and the egg until smooth.
- 3
Slowly pour the milk mixture into the flour mixture and stir with a spatula until a dough forms.
- 4
Knead the dough on a floured surface for about 5-7 minutes until it is soft and elastic.
- 5
Place the kneaded dough into a greased bowl, cover it with a clean cloth, and let it rise in a warm place for 1 hour or until it doubles in size.
- 6
Preheat your oven to 375°F (190°C).
- 7
Once the dough has risen, punch it down gently and divide it into 12 equal pieces, shaping each into a ball.
- 8
Place the dough balls on a lined baking tray, leaving space between each. Cover them again for 30 minutes to rise.
- 9
Cut a shallow slit along each bun, moisten the remaining sugar with a few drops of water, and mound it into the slits for the traditional crust.
- 10
Bake in the preheated oven for 15-20 minutes, or until golden brown and cooked through.
- 11
Once baked, remove from the oven and cool slightly before serving.

Storage Tips
- Store in an airtight container to maintain freshness.
- Reheat in the oven for a few minutes to restore the original texture.
- Avoid leaving the buns out in humid conditions.
Substitutions

- You can replace unsalted butter with coconut oil for a different flavor.

- Hot chocolate or coffee for breakfast.
- Fruit preserves or jam as a sweet accompaniment.
- A side of fresh fruit for a lighter meal.
Common Mistakes
- Not kneading the dough enough for a good rise.
