Bake them as a loaf or individual rolls. The recipe suits best for 9x13 inch pan that would easily accommodate 18 rolls, each placed about1 an inch apart. Or two 9 inch round pans. ( I have used an 11x7 inch pan for 13 rolls, and the rest I have baked as individual buns.)
You can choose to bake them as individual buns. (They make excellent burger buns.) Place them far apart from each other on a parchment-lined baking tray.
Cover and let them rise for 2-3 hours or until they fluff up in a warm place. If baking them as a loaf, which is the recommended way, they should rise well (more than an inch ) above the rim.
Towards the end of the proofing, preheat the oven to 360 0F.
Once the oven reaches the desired temperature, place a pan with hot water on the lower shelf.
Now, carefully transfer the pans/ trays to the oven. Take care not to press the risen dough.
Once the bread has been baking for 10 minutes, turn the baking pans/tray and give the bread a generous milk wash.
Then, bake the bread for 30 minutes more or until it turns golden brown.
When done, remove from the oven and let them cool for 5-7 minutes before transferring the loaf onto a cooling rack.
Enjoy the bread warm or let this airy Hokkaido milk bread cool completely before storing.
