Any ideas how long you can leave a dough out before it goes bad. It's already risen and ready to be punched down, but I don't want to actually cook my pizza for another hour or so....
Dough is essentially bread. You could leave it for several days and it'd be fine. If you refridgerate it it's good for weeks (re: no knead). Wait as long as you like, you'll be fine.
the two problems that can creep up over time are over stimulation of Yeast,[ in other words it will taste really yeasty] and the dough drying out. To slow down the yeast, put it in the fridge cold slows the action and the growth of yeast. As for drying out, cover it with a damp cloth or put it in a lightly oiled covered bowl
I make a batch of pizza dough, roll them all out and then freeze uncooked. Then just pull out of the freezer and they defrost in minutes.
