Say hello to the world’s biggest hamburger

Mad chefs at the Alameda County Fair (in America, obviously) have created the world's largest commercially available hamburger.

The monstrosity came in at a massive 777-pounds.

Officials from Guinness World Records were on-hand at the fair, in Pleasonton, San Francisco , to verify that the burger was bigger than the previous record holder - which weighed a mere 595-pounds.

The whopping whopper was the brainchild of Brett Enright from Juicy's Outlaw Grill in Phoenix and Nick Nicora from local company Ovations Food Services.

Enright dreamt up the idea while off work back in December. He told a local news station. "I thought, 'I bet I could build the world's largest burger', so I looked it up."

"The old record was held in Canada and we wanted to bring it home to America on the 4th of July."

It took Enright and his team 15 hours to cook the enormous patty, itself weighing 625-pounds.

They started cooking at 5am to have it ready for 8pm. A local welder was drafted in build a custom-made rig to help flip the patty.

Portions went on sale for 99c, with all the proceeds going to charity.

The sandwich's trimmings included a 110-pound bun, 20 pounds of onions, 12 pounds of pickles and 30 pounds of lettuce.

If you compare the weights, it's the equivalent of 1540 MacDonalds Big Macs (which weigh in at half a pound each).

The burger contains around 1,375,000 calories enough to feed one person for almost two years.

It would take that one (un)lucky person around 2,800 hours of jogging to burn off those calories.
