Gordon Ramsay joins the MasterChef Australia kitchen for a week-long guest judge stint. In the Mystery Box challenge, the contestants must use the ingredients Gordon has selected to create a dish that meets his high standards. A handful of the amateur cooks rise to the occasion, but others crumble under Gordon’s intense scrutiny and serve dishes that are inedible. In the second round, the contestants must wow with their twist on a classic dish, a burger and a side. The top three cooks from across the two rounds will fight it out for immunity. The bottom three head to Elimination, where one of them will be sent home. Show less
