Pizza dough didn't rise — the fix
Flat, dense dough hours later is disappointing but rarely hopeless. Three things stall a rise — yeast that's dead, yeast that's too little, or a kitchen too cold to let it work — and you can usually still bake something good.
Dead or expired yeast
How to tell — It never domed at all, and a spoonful proofed in warm water doesn't foam in ten minutes.
Fix it now — If the yeast is dead, start over with a fresh packet — and proof it in warm water first to be sure it's alive.
Next time — Keep yeast cold and sealed, mind the date, and learn the dose so a tiny amount isn't mistaken for none. the yeast guide goes deeper.
Too little yeast for the time and temperature
How to tell — It rose, just not enough — and your kitchen is on the cool side or the rise was short.
Fix it now — Give it more hours somewhere warm; a sluggish dough is often just a slow one, not a dead one.
Next time — Let the calculator weigh the dose for your actual hours and temperature — it scales the pinch to the plan, not the other way around. the yeast guide goes deeper.
The kitchen is too cold
How to tell — Everything was measured right, but the room is chilly and the dough is barely moving.
Fix it now — Find a warm spot — an oven with just the light on sits around the right temperature — and give it time.
Next time — Warmth speeds fermentation and cold slows it; plan the hours for the room you actually have. the cold ferment guide goes deeper.
Start from a good recipe
Most dough problems are planned away, not fixed at the bench. Set your real schedule in the calculator and it weighs the dough and writes the timing for you.
The clock is a suggestion. The dough is the boss. In bocca al lupo!
