Brett Enright of Phoenix grilled up the huge burger at the Alameda County Fair in Pleasanton, Calif., Saturday, the Contra Costa Times of Walnut Creek, Calif., reported.
He came up with the idea in December, his month off from his day job as chief executive officer of Juicys traveling barbecue catering service.
"I thought, 'I bet I could build the world's largest burger,'" he said. "So I looked it up."
He found that the previous record for the biggest burger was at 590 pounds.
So he contacted Nick Nicora, co-owner of Ovation Food Services in Pleasanton, and they teamed up for the record-breaking burger burn at the county fair Saturday.
They began cooking it at 5 a.m. and it wasn't quite done until 8 p.m. Bystanders paid 99 cents for a taste, with proceeds going to the Alameda County Community Food Bank.
