The series will kick off with four Heat weeks, each with three episodes, all aimed at testing the celebrities' skills. In the first Heat, five contestants will face the Under The Cloche challenge, before they then deliver a two-course Dinner Party Menu. Later, they'll step inside the world of professional cooking to come up with their own food truck dish. In the Quarter-Finals, they'll face critique from returning champions and finalists.

After Heats, eight successful celebrities will face up to what Semi and Final Week have in store, including a new Pizza round, a lavish feast on the British Pullman Train and a tricky brief of cooking something they don’t like to eat.
