In this series hosted by Sheree Murphy, each episode sees one of Britain's best chefs choose their perfect partner from four amateur home cooks, with the four teams then going head to head in a final. In this episode Michelin-starred chef Theo Randall has his eye on the prize as he puts four home cooks through a series of culinary challenges, including how to make the perfect potato rosti. Theo will be judged by triple Michelin-starred chef Pierre Koffmann in the final, so his professional pride is at stake. But which home cook will he choose?
