Billie, Jessie, Reynold and Sara cooked off for guaranteed immunity and the Power Apron in a duel-based challenge: contestants would face each other in three rounds, one vs. one, with a different cuisine and protein each round. In the first round, Reynold, as holder of the Power Apron, chose Jessie as his opponent cooking a French dish with pipis, but it was Jessie who won the round. In the second round, Billie and Sara faced off cooking flathead in a UK-style, with Billie winning. Jessie and Billie then competed in the final round cooking a Chinese dish with chicken, with Billie's Twice-cooked Orange and Cinnamon Glazed Chicken beating Jessie's Hainanese Chicken Soup (27-24) giving her the Immunity Pin and Power Apron.
