This time, the Mistrys from south London take on the Whittakers from Lancashire, the Walker-Kings from Wandsworth and the Varmas from Walsall. All four families enter the Showdown kitchen totally unprepared for their first challenge - to make a £10 one-pot wonder with a surprise selection of ingredients. Their second challenge is to cook up their family's take on fishcakes. Taking both dishes into account, judges Angellica Bell and Tommy Banks decide which three families can cook for them again in next day's heat.
