Carnival Cruise Line has unwrapped details of its new Boomerang Burger, which is set to add a true Australian flavour to Carnival Spirit’s new burger bar – and keep guests coming back for more.

Created by American chef, restaurateur and Food Network personality Guy Fieri, it’s tipped to be a favourite at Guy’s Burger Joint, which debuts on Carnival Spirit in September.

The Boomerang Burger will feature beetroot – the standout ingredient nominated as a must-have by local cruisers – alongside other Aussie favourites like tasty cheese, bacon, tomato and grilled onion.

Better yet – it’s free!

To meet the beetroot challenge, Guy developed a special beetroot relish that will feature on the Boomerang Burger in addition to his trademark Donkey Sauce, a blend of tomato relish and aioli.
