Cafe claims world's biggest burger

SYDNEY patty that took 12 hours to cook and four men to flip.

The monster burger cooked up by Sydney cafe owners, Joe and Iman El-Ajouz, weighed in at 90 kg in total, eclipsing the previous record of 84 kg, set in Michigan in the United States.

"Just flipping the patty was the main challenge for us, but it all went well," Iman El-Ajouz told Reuters.

"My husband had to prepare special metal holders and a metal plate, he had one at the bottom one at the top, locked them together and they flipped the burger with that," she added.

The giant burger contained the giant beef patty, 120 eggs, 150 slices of cheese, 1.5 kg of beetroot, 2.5 kg of tomatoes and almost 2 kg of lettuce all topped off with a special sauce on a giant sesame seed bun. It was eaten by employees at the cafe.

The variety of burger will be on the menu at the cafe for the next year in order to meet the conditions for a Guinness world record, but will set hungry patrons back around A$1,500 .
