Instructions
In the bowl of a stand mixer, combine the 2 tablespoons warm water and the 7g yeast. Let sit for 10 minutes, or until the mixture becomes bubbly. Stir well.
In a small saucepan, whisk the 40g flour and the 200g liquid (60ml water + 140ml evaporated milk) together until smooth with no lumps. Cook over medium-low heat, whisking constantly, until it thickens into a smooth, thick paste, about 2 to 3 minutes. Remove from heat and let it cool to room temperature before using.
In a large bowl, combine the remaining 395g flour, sugar, salt, and powdered milk.
Add the beaten egg, remaining 100ml evaporated milk, melted butter, and the cooled tangzhong to the proofed yeast.
Slowly mix in the dry ingredients until a shaggy dough forms, then knead until smooth and elastic: about 15 minutes by hand, or 10 to 15 minutes on a stand mixer, speed 3.
Form into a ball, then transfer to a bowl. Cover with plastic wrap or a damp cloth. Let rise in a warm place for about 1 to 2 hours or until doubled in size. Tangzhong dough can get there a little faster, so start checking around the 1-hour mark.
Punch down the dough to remove air pockets, then transfer to a floured surface. Form into a log and divide equally into pieces, about 50 grams each. Keep unused pieces covered while you work.
Gather all sides of a piece of dough and tuck under to form a ball. On a clean, unfloured surface, cup your hand loosely into a U shape over the dough and rotate it with light pressure until it's smooth and round.
Coat with bread crumbs, then arrange on a pan, leaving an inch of space in between. Cover and let rise again for another 30 to 45 minutes.
Preheat oven to 350°F, then place the baking sheet on the middle rack and bake for about 18 to 22 minutes. Tangzhong doughs can brown a little faster from the added moisture, so check at the 18-minute mark first.
Cool slightly before serving warm.

Notes
Prep and total time are estimates.
Rise times can run 1 to 1.5 hours for the first rise and 30 minutes to 1 hour for the second, depending on how warm your kitchen is.
Dough can be refrigerated overnight after the first rise.
Baked rolls freeze well for up to 1 month in an airtight bag.
