Donut bacon burger stops traffic, hearts

A greasy bacon-covered beef burger that uses a honey-glazed donut for a bun has become the runaway hit of a US food fair.

The 1500-calorie "Craz-E Burger" stunned organisers of the Big E fair in West Springfield, Massachusetts, as fat-loving foodies walked away with about 17,000 of the over-the-top treats during the event's 17-day run.

The burger — believed to have originated in the US south — has been largely credited with attracting the most visitors to the fair in its 11-year history.

And most people who ate the burger appeared to give it the thumbs-up.

"I went last week and tried the Craz-E Burger. It was delicious. Try it!" one consumer, Triliflops, wrote on Twitter.

Another wrote: "Oh my good god the craz-e burger was amazing ... now I have to live with myself knowing I ate a cheeseburger with bacon on a donut."

One of fair's organisers said she was amazed by the burger's popularity.

"There is just something about it that makes it a fun fair food," Boston Culinary Group general manager Maureen Jordan told US website masslive.com.

"It wouldn’t necessarily work in a restaurant or another setting, but at the Big E it’s just right."
