For the main course, all three chefs are cooking Welsh lamb in the hope of impressing this week's veteran judge. Nick Brodie, head chef at Llangoed Hall in the Brecon Beacons, is known for his use of local Welsh produce. He is using summer lamb to produce a modern update of a classic dish which he hopes will triumph over the other two. Phil is taking a risk with barbecued lamb and in an attempt to elevate a humble barbecue to banquet level, he is serving it with many accompaniments. But will he be able to bring everything this together and cook his lamb to perfection? Paul surprises the veteran chef with a number of unusual ingredients to accompany his lamb. Will Paul be able to pull off these unusual flavour combinations and find himself at the top of the scoreboard?
