Is this the end for blackened burgers? New 500c barbecue oven can cook your meat in a third of the time and knock up a pizza in just 90 seconds

Roccbox can cook stone-baked pizza, sausages, hamburgers and kebabs in less time than it takes to make toast, removing all the frustrations of a traditional barbecue. 

It is ready to use in just 15 minutes and can bake a crisp 12-inch pizza in 90 seconds, as well as roasting meat, fish and vegetables, and even baking crusty bread. 

More than 116million barbecues were fired up last year, with all too many taking ages to get to the right temperature. 

The result? Ritual offerings of meat burnt to a crisp on the outside yet raw in the middle. According to the makers, who are based in Dorset, that won't happen with the Roccbox.
