The cooks have an hour and three quarters to prepare their ultimate fish dish with delicious accompaniments designed to showcase their individual personality. The cooks embrace the pescatarian brief in a creative and innovative fashion, rustling up globally inspired dishes including a Filipino exploding fish, Asian-inspired gurnard with wontons, Indian spiced seabass with a prawn curry, as well as more classic salmon hollandaise, butter-poached halibut and a decadent seafood pasta.Next, it's the 'Cooks' Challenge' which tests inventiveness and creativity with a key ingredient. The cooks with the finest fish from challenge one are given the advantage by the judges and will determine the key ingredient in the next round for everyone. This time, the choice is between rice or squash, a conundrum for any confident cook especially as they have no prior knowledge of the other ingredients they'll have in their kitchens.The next morning the cooks return to their freshly stocked kitchens to invent a sweet or savoury dish in one hour celebrating the central ingredient. While there are some standout dishes, a few miss the mark with their creative interpretations.In the elimination round, the judges have chosen a tricky dessert that requires precision and any lack of concentration could lead to an early exit.

The search continues as Mary Berry, Dan Doherty and Chris Bavin, put the remaining eight home cooks through the culinary ringer. Hosted by Claudia Winkleman, the cooks move between their house with their fellow friends and the kitchen where they must compete in this week's challenges set by their three demanding judges. As usual, the cooks have to perform to their very best in the first two challenges if they are to avoid the elimination round and risk being sent home.

The cooks have to prepare their ultimate roast with a potato dish and at least two other vegetable accompaniments designed to showcase their personality. Civil servant Dipa tries out her unique spin on the traditional roast using spices, while Welsh mum of four Katie opts for an ox heart. Farmer Trevor cooks with one of his own reared flock, while maths teacher Philip makes yorkshire puds with rosemary.
