Episode 4

Tonight, the three remaining families face a surprise head-to-head challenge for which they have to nominate one family member to cook on their own. There are pastry disasters, fruit controversy and raw egg whites as the cooks tackle a lemon meringue pie. For the second task, the families are reunited to make a two-course meal with lamb and almonds as the star ingredients. The pressure is on as only two families can make it through to Friday's playoffs.
