Episode 1

Marcus Wareing, Monica Galetti and Gregg Wallace return as six aspiring chefs battle it out for a place in the quarter-final of the cookery competition.

The first three chefs are challenged to make the classic French dessert ile flottante, or a floating island, requiring them to make perfect custard and meringue. The other three must prepare a blue steak with a green peppercorn sauce - they only have 15 minutes and the steak must be cooked exactly right.

Finally, the six can showcase their creativity by presenting their own signature dish. Half the group will be sent home with only three competitors progressing.
