In the U.S., the Alameda county fair in Pleasanton California cooked up the world's largest hamburger on Sunday.

America has reclaimed the record for the world’s heaviest beef burger – with this 777 lbs monster which contains 1.3 million calories.

The record-breaking whopper, including bread, vegetables, and sauces, weighed a sizzling 352 kilograms, that's 85 kilograms bigger than the previous record holder from Canada.

A 10-person crew cooked the burger for 13 hours, flipping the monster patty every hour on what organizers claimed was the world's largest grill.

Fair officials are waiting for the Guinness World Records to certify the results.
