Four chefs cook, while the other four taste and score their dishes in a blind tasting, with Andi as referee. The roles are then reversed as they take it in turns to both cook and score.With only three chefs out of the eight going forward to cook for the judges in tomorrow's episode competition is hot, and the standard of cooking world class, as the chefs unite to create unforgettable dishes for Britain's key workers.
