Dough did not rise
Makes the pizza unusableUsually a yeast-activity or temperature problem, rarely a recipe-ratio problem.
Ask yourself
- How old is your yeast, and was it stored correctly?
- What was the water temperature when mixing?
- How warm was the room or proofing spot?
Likely causes
- #1
Dead or inactive yeast
Strongly supportedYeast loses activity over time, especially once opened, and is killed outright by water above roughly 50C.
- #2
Room or dough temperature too cold
Strongly supportedYeast activity slows dramatically below about 15C, extending fermentation time well beyond a typical recipe's estimate.
- #3
Too much salt in direct contact with yeast during mixing
Generally acceptedSalt is osmotically harsh to yeast cells if added directly onto them before mixing disperses it.
Rescue it now
Move the dough somewhere warmer (around 24-27C) and give it more time; if yeast is suspected dead, a small proofed test batch confirms before discarding the whole dough
Prevent it next time
Proof yeast in warm water with a pinch of sugar before mixing if in doubt, and check your yeast's use-by date
