Prepare the Tangzhong
The tangzhong is the secret to exceptionally soft, fluffy dinner rolls. Cooking a small portion of the flour and water before mixing the dough allows the flour to absorb more moisture, producing rolls that stay fresh for days.
Whisk the bread flour and water together in a microwave-safe bowl until completely smooth. Microwave in 30-second intervals, whisking thoroughly after each interval, until the mixture thickens to the consistency of pudding.
Allow the tangzhong to cool for a few minutes before moving on to the next step.
