Why aren't my bao buns smooth?
A rough finished surface does not point to one cause. The useful clue is when the surface stopped being smooth: during mixing and shaping, during proofing, or only after steaming.

The final symptom is not the cause. Use the details you can actually observe to narrow the next test.
Use the timing and the strongest visible clue.
1. Rough before steaming?
Start with dough development and shaping. A short rest between kneading rounds can make a smooth dough easier to achieve, and a medium-firm smooth dough is a common target in mantou methods.
2. Smooth before steaming, rough after?
That moves steaming and proofing higher. Over-proofed buns can lose surface quality when their internal structure becomes fragile.
3. Pitted or wet-looking surface?
Visible droplets are a different clue. Condensation dripping from a metal lid can damage an otherwise smooth surface.
Take a photo immediately before steaming and another immediately after. If the surface is already rough before steaming, test dough rest/kneading. If it changes only in the steamer, keep the dough formula fixed and test proof endpoint or condensation control.
Evidence: Red House Spice — smooth dough, proof state and collapse; King Arthur Baking — condensation control.
Quick answers
Why are my bao smooth before steaming but bumpy after?
That makes shaping alone less likely. Check proof state, condensation, and steaming conditions.
Does a rough surface always mean I kneaded badly?
No. Roughness that appears only after steaming can come from a different stage.
What photo should I take?
Take one close top photo before steaming and one immediately after. The timing of the change is diagnostically useful.
Let the next batch answer one question.
Bao Rescue asks a few observable questions, keeps weak evidence weak, and gives one next-batch test instead of a long list of generic fixes.
