Last Tuesday I forgot to freeze two leftover Detroit style dough balls. On Friday I saw them in the deli cooler. They had risen a lot and I thought I would then freeze them. I forgot them again. Today they were still in the cooler. I inspected them and although they had deflated, they still had strength in the dough and some bubbles when they were pressed on. They smelled good, so one dough ball was incorporated into each of the two batches of dough, along with some partially frozen boardwalk style dough balls. The boardwalk style dough batches didn't seem to change.
