My Japanese milk bread recipe makes ultra-soft, fluffy Hokkaido rolls with tangzhong—lightly sweet, stays fresh, perfect for sandwiches.
In a small saucepan, over low heat, add the water, milk and bread flour and whisk until thickened, 2-3 minutes.
Remove the mixture from the heat and set aside to cool.
In the bowl of a stand mixer fitted with a dough hook, add the bread flour, sugar, milk powder, yeast and salt and stir to combine.
Add the Tangzhong, milk, egg and butter, and knead on medium-low speed for 8-10 minutes or until a smooth, elastic dough forms and clears the sides of the bowl. (This step can also be done by hand)
Transfer the dough to a large, oiled bowl. Cover with plastic wrap and let rise until doubled, 60-90 minutes.
Gently deflate the dough, divide it into 10 equal pieces (roughly 75g each), and shape each piece into a ball.
Place the rolls into a lightly greased 9" round cake pan. Cover the pan with plastic wrap and let the rolls rise until doubled, 40 to 50 minutes.
Towards the end of the rising time, preheat the oven to 350°F (180°C).
Egg wash the rolls carefully and bake for 25 to 30 minutes, or until golden brown on top.
Remove the rolls from the oven. Allow them to cool in the pan for 10 minutes, then transfer them to a rack to cool completely.
These rolls are best enjoyed fresh, but you can store them at room temperature for up to 3 days. They also freeze really well for up to 2 months.
