Why are my bao buns dense and not fluffy?
Do not jump straight to “dead yeast.” First ask whether the shaped buns rose, then cut one open and compare the crumb. A tight dry crumb, a fluffy crumb, and a wet gummy crumb are different diagnostic signals.

The final symptom is not the cause. Use the details you can actually observe to narrow the next test.
Dense is an inside problem — inspect the crumb.
1. Did the shaped buns actually rise?
If they barely rose before steaming, diagnose proofing and yeast activity before blaming flour. Proof time is temperature-sensitive, so state cues matter more than a fixed clock.
2. Cut one open: fluffy, dense, or gummy?
A truly dense crumb has small gas cells and a tight, heavy structure. A gummy crumb is wet/glossy/compressed and should stay a Beta branch rather than being treated as ordinary density.
3. Was the dough much stiffer or the flour/liquid ratio changed?
Hydration and gluten structure measurably affect Chinese steamed bread quality. A direct stiffness or formula clue makes flour/hydration a stronger first variable than random extra proofing.
If rise was poor, test the proof endpoint. If rise was good but the crumb is tight and the dough was clearly stiff, make one measured hydration correction while keeping proofing and steaming constant.
Evidence: Journal study — hydration level, gluten network and Chinese steamed bread quality; Review — steamed bread production and gluten properties; Red House Spice — proofing and poor rise.
Quick answers
Does dense bao always mean dead yeast?
No. Poor yeast activity is one possibility, but under-proofing, flour/hydration mismatch, and dough structure can produce similar results.
How can I tell dense crumb from gummy crumb?
Dense crumb is tight and heavy with small gas cells. Gummy crumb looks wetter, glossier, compressed, or slightly translucent.
Should I add more water next time?
Only when you have a direct stiffness or formula clue. Make a measured hydration change and keep proofing and steaming constant so the comparison teaches you something.
