I have tried to save these without cooking and store them between parchment sheets. But I found that the longer the dough sat, the more the flour absorbed, and by the time I went to cook them, the dough was so sticky that it stuck to the parchment paper and ripped. At that point, I had to start over with the rolling. So I recommend that if you want to keep the dough stored without cooking, store the balls in an airtight container and refrigerate or freeze (depending on how quickly you’d like to use them).
