True taste of Australia on Carnival SpiritPeter Lynch·30 Jul 2015News·1 Comment·0 Share on Facebook Share on Twitter 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.
