ROME (AP) —

The wait was on the long side for the pizza — 18 hours — but this was an extraordinary pie: 1.59545 kilometers, or nearly a mile long.

More than 60 of Italy’s best pizza-makers worked through the night to create the pizza at Milan’s world fair, Expo 2015. Their toil was rewarded with a proclamation by Guinness World Records judge Saturday that it was the world’s longest pizza. Expo organizers said the record-setting pie, made with 1.5 tons of mozzarella and 2 tons of tomato sauce, weighed some 5 tons in all.

The creation topped the record of a 1.1415-kilometer-long pizza made in Spain.

Fair-goers could eat slices of the Milan pizza for free. Slices of long, rectangular pizzas with various toppings are a popular street food in Italy.
