Mamma Mia that's a lot of pizza! Measuring 1.8km long, this cheesy masterpiece took 250 people six hours and 11 minutes to make. Using 2,000kg of flour, 1,600kg of tomato sauce, 2,000kg of mozzarella cheese, 200 liters of oil and 30kg of basil, the pizza wrapped its way around the Naples coastline in Italy. Once it was cooked it was given out to disadvantaged people in the local community.
