Mike;
Here’s another approach that I’ve had good success with in small stores. Get a 30-gallon plastic barrel with a lid approved for food contact. For a 50# flour basis dough size, make a sponge using 30# of flour, 15 to 16# of water (cold) and 0.75-ounce of instant dry yeast. Place these ingredients in the mixing bowl and mix at low speed for about 7-minutes then transfer to the barrel which has been lightly oiled inside. Cover and set aside to ferment overnight. I recommend making the sponge each night just before closing. The sponge will be ready to use on the following day. To make your dough, transfer the fermented sponge to the mixer, add 20# of flour, 14-ounces of salt, 12-ounces of sugar (optional), 2-ounces of instant dry yeast, 13 to 14-pounds of water (75F), 16-ounces of olive oil. Mix at low speed for 2-minutes without the oil, then add the oil and mix just until you achieve a smooth dough consistency/satiny appearance. You are looking for a finished dough temperature of 80 to 85F. After mixing immediately scale and ball, place into dough boxes, wipe the dough balls with a little salad oil, and place in a reach in cooler for at least 2-hours before using. The dough will keep all day in the reach in. Just be sure to stagger/off set the boxes as you place them in the reach in to allow for more effective cooling. After about 2-hours the boxes can be nested to prevent drying. This process gives a finished crust with improved flavor over same day dough and it is about as close to bullet proof as one can get.
