My pizza prep fridge did keep the lower temperature, from Monday to Tuesday this week. I still am not sure what happened that my pizza prep fridge acted up last week, but think it might have been my pizza prep fridge was pushed against the wall. The vent where the heat goes out is in the back. The wheels are locked on the pizza prep fridge, but the fridge can be pushed back, without too much effort.
It seems like the 25 minute at 110 degrees preferment heat-up on Friday, in the Hatco Unit, is going well for the preferment. There was no trouble opening the dough balls yesterday.
Picture of dough balls in the pizza prep fridge yesterday, a few pizzas make yesterday, two regular preferment Lehmann dough pizzas made with reballed overfermented dough from last week that was frozen, and another Greek Pizza made with the preferment Lehmann dough. I would like to add more cheese on the Greek pizzas, but since cheese is becoming more expensive, I only add what I think I need. The dough for the Greek pizzas was really rolled out with a heavy rolling pin and docked heavily, but as can be seen the rim still want to rise.
