It is then time for the cooks' challenge, which tests their inventiveness and creativity with a key ingredient. The cooks with the best chocolate from challenge one are given the advantage by the judges as they determine the key ingredient in the next round, choosing between aubergine and tofu. The cooks must then invent one dish celebrating the central ingredient and have one hour to win over the trio of judges and avoid the elimination round.

It is week six, and Mary Berry, Dan Doherty and Chris Bavin test the remaining five home cooks on their finest dishes. The cooks have two and a half hours to prepare their ultimate sharing feast, which must contain at least four dishes designed to showcase their individual personality. The cooks are up against it as they try to impress the judges with the complementary dishes that must come together as a complete meal.

It's the semi-final and Mary Berry, Dan Doherty and Chris Bavin continue to test the last four home cooks. The semi-finalists have two and a half hours to prepare their ultimate drinks party with a selection of four savoury canapes, one sweet canape and a drink designed to showcase their individual personality. Then it's the cooks' challenge which tests their inventiveness and creativity with a key ingredient. The cooks with the most perfect drinks parties from challenge one determine the key ingredient choice between orange or ginger. In the morning the cooks return, and in just one hour must win over the judges and avoid the elimination round. Based on their performance in these two challenges, the judges decide who deserves to be in the final and who must cook again. The judges have chosen a classic Italian dish that requires precision, care and skill. At the end one cook must part from the group, leaving just three finalists in contention for the title of Britain's best home cook.
