How quickly do I have to use my thawed pizza dough? I have never used frozen pizza dough before so I didn't know how long it would take for it to thaw out. I plan on using it tonight for dinner (in about 7-8 hours) and I thought it would take much longer for the rock hard dough to thaw out. I have had it covered and sitting on the kitchen counter and it's almost completely thawed out!

So once it's thawed can I keep it in the fridge until I'm ready to use it?
The short answer is yes, you can keep it in the fridge until you're ready to use it, up to 4-5 hours I would think. It will be too cold to over-ferment. It's better to defrost it in the fridge to avoid it getting too warm.
