Cooking such a large burger might seem to be a frivolous endeavor, but fair organizers say it is for a good cause, as individual bites will be sold for 99 cents, with the proceeds going to the Alameda County Community Food Bank.
The 99-cent price is in celebration of the fair's 99th consecutive year of operations.
Trying to break the record is serious business, as officials from the Guinness Book of Records will be on hand to verify that the burger is bigger than the 595-pound burger that currently holds the record.
The burger is expected to be 1,375,000 calories, which is enough to feed one person for about 22.5 months.
The trimmings will include a 110-pound bun, more than 50 pounds of cheese, more than 20 pounds of onions, more than 12 pounds of pickles and 30 pounds of lettuce.
The burger will be cooked on the world's largest barbecue, which is owned by Juicys, a mobile food and beverage business that serves large events such as the Kentucky Derby, car races, rodeos and fairs.
Juicys owner Brett Enright said Friday that trying to cook the world's largest burger was his idea, as he likes the idea of having "a mega event" and trying to break a record.
"It's a fun project," he said.
Enright said cooks will begin preparing the burger at 5 a.m., and at 6 a.m. they will start cooking it on a huge fire pit grill mounted on an 18-wheel, 72,000-pound truck.
"It looks like a big tanker," Enright said.
He said cooking the burger will take about 10 hours and that a large crane will flip it halfway through the process.
The burger will be tested around 4 p.m. to make sure it is done, and then Guinness officials will verify its size.
Once all that is done, cooks will slice off chunks of the burgers to sell to fairgoers who want to taste a piece of history.
