Why aren't my bao buns rising?
If the shaped buns stay small, do not jump straight to “dead yeast.” First separate whether there was almost no fermentation, some rise but not enough, or a normal first rise followed by weak final proof.

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. Almost no rise at all?
Yeast activity and dough temperature become important checks. A fixed proofing time is unreliable because room temperature changes fermentation speed.
2. Some rise, but buns still stay small?
The final proof endpoint may simply be early. Well-rested buns should look slightly larger and light, rather than being judged only by the clock.
3. Dough unusually stiff?
A very firm dough can reduce expansion and may reflect a flour/liquid mismatch. Hydration affects gluten network development and steamed-bread quality.
Keep the recipe unchanged and proof by state instead of time. Record room temperature and stop the test when the shaped bun is visibly lighter and slightly larger. If there is still almost no rise, test yeast activity next.
Evidence: Red House Spice — proofing time, temperature and poor rise; Study — hydration and gluten-network quality in Chinese steamed bread.
Quick answers
How long should bao proof?
There is no universal clock time. Temperature and dough state matter, so use visible and tactile proof cues.
Does no rise always mean dead yeast?
No. Yeast activity is one branch, but cool temperature, early proofing, or unusually stiff dough can create similar results.
Should I add more yeast next time?
Not before isolating the cause. First confirm whether the current yeast is active and whether the dough reached a reasonable proof state.
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.
