Ingredients
For the tangzhong
- 2 tablespoons water
- 4 tablespoons milk
- 2 tablespoon flour
For the bread
- 2.5 cups all purpose flour
- 1.5 tablespoons active dry yeast / instant yeast
- 1/4 cup of sugar
- 1 teaspoon salt
- Tangzhong mixture
- 1/2 cup of milk
- 1 egg
- 3 tablespoons unsalted butter (room temperature)
To make the tangzhong mixture, combine the water, milk, and flour in a small saucepan over medium heat. Stirring constantly so the bottom doesn’t burn, the mixture should thicken after a few minutes (you’re looking for the consistency of a paste that is no longer runny). Set aside to cool.
In the meantime, combine the rest of the flour, yeast, sugar, and salt. Give it one thorough mix to ensure the equal distribution of the dry ingredients. Add the milk, egg, and cooled tangzhong and mix until the dough comes together into a rough ball. The dough should be sticky, but if it feels too wet to form a ball, add a more flour as necessary. Knead the mixture (or use the dough hook feature of a stand mixer) until the ball is smooth; this should take about 10-15 minutes. Add one tablespoon of room temperature butter at a time to the dough and continue kneading until it is completely incorporated. Once all the butter is added and the dough is smooth, cover with a damp cloth or plastic wrap and let proof for 30 minutes (or until the dough has doubled in size).
Once the dough finishes its initial proof, divide it into three equal pieces. Roll out each piece into a long rectangle (~9 inches long / ~9 inches wide). Fold the two sides of the dough toward the center one after the other so you end up with a shape that is still ~9 inches long but now only 3 inches wide. From there, roll the dough up in a spiral shape to form a small cylinder. Repeat with the other pieces and place all three in a loaf pan (the open/spiral part of the pieces should be facing the sides of the pan). Proof one more time for another 30-40 minutes.
Before baking, you can either add an egg wash to the top (as pictured) to create the shiny/mounded look, or add the loaf pan cover so when the dough expands as it cooks, it forms a more uniform square shape. Regardless, bake in a 350 degree fahrenheit oven for 30 minutes or until golden brown. The bread is best enjoyed right after it cools, but if you need to refrigerate/freeze any leftovers, a quick toast will make it good as new!
