It would be enough to immobilise most of us but the Junee Licorice and Chocolate Factory is challenging you to eat all that and more in the form of its one kilogram ‘Impossible Burger’.

Completing the challenge in less than 15 minutes will land punters the meal for free, with the best performers to compete at next month’s Rhythm n Rail Festival.

Burger enthusiast Lachlan Macaulay was the first person to tackle the cheesy monstrosity, but wasn’t able to finish his chips in the allotted time late last week.

Mr Macaulay remained defiant in defeat.

“I’m not overly full, I just needed more time to finish,”  he said in the aftermath.

“Another five minutes and I probably could’ve knocked it over.

“I think I’ll still poke away it, just to finish it off.”

Factory owner Neil Druce said the burger challenge was the result of his ongoing quest to find new ways to keep the public engaged.

“We’ve looked at chocolate eating competitions but you don’t want people to get sick,” he said.

“I’m not sure why, as a nation, we’re so interested in how much you can eat in a short period of time, there are probably other measures of a person.

“But it's a bit of fun and the staple thing to do.”

Mr Druce hopes to have 100 people tackle the Impossible Burger before Rhythm n Rail kicks off.
