Don't skip the tangzhong – it's the key to soft rolls. Use a serrated knife for clean cuts. Check the center rolls for doneness with an instant-read thermometer. Let the glaze set for 5 minutes before serving. The filling is forgiving even if it leaks a little. For make-ahead, assemble rolls in the pan, cover, and refrigerate up to 12 hours; let come to room temp before baking. Freeze unglazed baked rolls for up to 3 months.
