In today's immunity challenge, Sarah T, Laura, Jess and Callum will compete in a reverse auction, bidding for ingredients from four different categories: protein, miscellaneous, fruit and veg, and herbs and spices. The time they bid will be deducted from their cooking time. The contestants then have to cook using at least one item from each of their purchased categories.
