Rachael, Brent and Renae compete in the first round, taking turns of naming different cheeses. Renae and Brent failed to answer their next guesses, and Rachael won the chance to cook for immunity against chef Matt Stone from Greenhouse in Perth. He chose cheese (over ham) as the core ingredient. In one hour, he cooked a Carrot and Manchego salad while Rachael cooked a Lobster Mornay and Cheese Soufflé with Grilled Mango. Matt’s salad was praised for the quality of the dish and highlighting the core ingredient, but lacked balance to taste. While Rachael’s dish earned praises with her lobster and grilled mango, the conflicting flavours to her cheese soufflé on her dish meant she lost with the lowest score of 15 to Matt’s 23.
