The two highest-scoring chefs from Wales must go head-to-head and cook their six-course menus again. Will they take on board their veteran's advice as they serve to the new panel of judges?
They need to impress Michelin-starred chef Marcus Wareing, chef and restaurateur Nisha Katona, and comedian and food podcaster Ed Gamble. There's also the guest judge, TV presenter Gethin Jones, who spent his life around animation at S4C before moving to Blue Peter. How will he judge dishes inspired by British animation and illustration and Paddington's 65th birthday?
Only one of the chefs will triumph and go through to represent Wales at the national finals.
Despite BBC 2 official info, Tom Kerridge was back in his regular season 18 judging job, not Marcus Wareing.
