The second heat continues with the four remaining celebrities facing three more culinary challenges, as they battle for a place in the semi-finals. The first challenge is the new Pairs Challenge, where the four celebrities are split into two teams of two. Each team is tasked with cooking the same dish. Both plates must be identical in appearance and flavour, but there is a catch - in-between each pair there is a wall. The only way for the celebrities to successfully produce identical plates is by communicating with their teammate through the wall.
