Three chefs fight for survival in the first elimination challenge. They are given 75 minutes to cook a dish with ingredients from their home fridge and pantry.

The top 24 try to stand the heat in the kitchen, with 90 minutes and an open pantry to cook their dishes and impress the judges, focusing on hospitality.

It is the first mystery box challenge, with one contestant choosing eight ingredients for chefs to cook from and make a dish in 75 minutes.

The three contestants on the bottom after the invention test go head-to-head in a pressure cook off, while Maggie Beer presents their new challenge.

Nigella Lawson returns as the guest judge with her choice of mystery box ingredients, including marsala, chicken livers, squid and condensed milk.

On the last day of Gordon Week, the team who has lost the service challenge must cook to stay in the competition.
