Roberto's Pizza Passion in St. Catharines, Ontario, Canada have cooked arguably the World's longest Calzone! The base of it was created with 71 pieces of dough, weighing about 2.5 pounds each. Combined with all of the oil, sauce and toppings, the weight was estimated to be between four and five hundred pounds. The raw calzone was measured to be just over 39 feet and after it's run through the oven, had a measurement of 38 ft 10.25 inches by 2 ft 3.75 inches. Absolutely epic!
