One of the most renowned chefs in the world, Ken Hom, visits the MKR Mansion, where Edinburgh couple Angela and James face the challenge of creating an impressive main course from Ken's mystery ingredient: whole salmon. The couple's love of the Far East and passion for Vietnamese cuisine leads them to produce a dish called salmon bun cha, in which the salmon is filleted, skinned and cooked in various ways. They end the meal with an orange tart with Vietnamese egg coffee. But will their efforts stand the test of the challenge?

Today, it's the turn of microbrewery boss Ray and colleague Simon to create a dazzling main course for 11 guests using the mystery ingredient saddle of Welsh lamb, presented by their guest judge Stephen Terry, professional chef and owner of the Hardwick in Abergavenny. The pair butcher and prepare the saddle to create a Moroccan-inspired dish with spiced potatoes and roasted vegetables, followed by a honey and lemon cheesecake with strawberries. But will their Mediterranean twist on a classic dish prove worthy enough?
