How can I make (pre-made pizza) dough sticky again?
I used some pre-made pizza dough bought from my local supermarket to prepare some pizza balls (basically pizza dumplings). A problem I encountered was that the dough was very non-sticky so that I couldn't easily close the balls. I tried to make the dough a bit more sticky with water but that led to the opposite effect of the dough being even less sticky. I also tried flour mixed with water and eggs which did help a little but not immensely.
In the end, I put the not-closable sides facing downards on the baking sheet so that the filling couldn't spill. It worked just fine but was obviously not how I intended it to be.
What is the best way to make a (pre-made pizaa) dough sticky again?
