In the opening episode we meet the Marks family from west London, hoping to impress with their Scandinavian-inspired dishes. Eighty six year-old grandmother, former model and fashion designer Torun was born in Sweden and came to the UK when she was 30 years old. Her daughter Jessica (55) is a nutritional therapist and mother of three children, including her eldest Oskar (29), who works at an independent record company.

The Marks family enjoy cooking Swedish dishes that Torun has passed down to her family, but Oskar tends to adapt the recipes using more exotic ingredients. Toren has a lust for life and rules the roost in the Marks kitchen - but will her age-old family recipe for Swedish meatballs hit the mark?

Facing them are the Charles family from Bridlington in Yorkshire, who take food inspiration from their travels across Europe and Asia to come up with new and exciting dishes. Betty (29) met her husband Dan (32) 12 years ago and they married in 2015 after Dan proposed to Betty while on holiday in Rome. Her mother Jean (59) often lends a hand in the kitchen and completes their team. Betty's the boss in the Charles family - but will her decision to serve up a risotto to Italian chef Giorgio pay off?

It's heat three of the competition, with two more families facing each other for a place in the semi-finals. This week the Pigotts from Oxfordshire go head to head with the Hilliards (pictured) from Essex.

Will the Pigott brothers and their bold, globally inspired flavours impress the judges, or will the classic home cooking of the Hilliard sisters and their mum be what Rosemary and Giorgio are looking for?
