FROZEN/FRESH DOUGH HANDLING TIPS

The following are general tips. Follow any instructions specific to your brand of dough or recipe.

• Remove the wrapping from frozen dough balls.

• Place the dough balls a few inches apart, into a proofing box or on a sheet pan.

• Lightly spray top of the dough balls with a non-stick cooking spray, then cover with a layer of freezer paper.

• Refrigerate overnight.

• Remove only enough dough balls from the sheet pan to accommodate what you will need for a few hours.

• Sprinkle flour, cornmeal or Pizza Crisp onto the surface on which you plan to roll out the dough.

• Roll the dough, starting from the center and working your way to the outer edges. Turn the dough as you work toward the outer edges to maintain a round shape.

• Use a rolling pin, dough press or dough sheeter to form the dough to the desired size and thickness.

• Place the flattened shell onto a dark metal or seasoned pizza screen or pan. NOTICE: Fresh dough pizzas must be baked on metal pizza screens or pizza pans. Do NOT put fresh dough pizzas directly on the conveyor. Dough will stick to or fall through the conveyor. NOTICE: Do NOT use paper pizza pans in this oven. Paper pizza pans will burn and could create a fire hazard. NOTICE: Dark metal or seasoned metal screens or pans perform best. Shiny metal or aluminum foil will reflect heat away from the pizza and preventing browning.

• Spread the sauce, starting from the center and moving toward the outer edges of the crust to ensure a uniform thickness of sauce. Leave an inch of space to the outer edge of the crust to allow the crust to brown. Spreading sauce too close to the edge prevents the crust from browning.

• Spread out high moisture content toppings, such as vegetables. High moisture toppings will prevent the surrounding areas from baking until ALL of the moisture has evaporated.68 Inch Digital Conveyor Pizza Ovens Operator’s Manual – Model MGD 3 FEATURES
