This week's competition is in Edinburgh, where the first to host is 27-year-old interior designer James. James is banking on blowing away his guests with his spicy Mexican menu, with big portions and bold flavours. The guests he's eager to impress are 31-year-old lawyer Aisling, 29-year-old nursing lecturer Bruce, 69-year-old retired restaurant manager Katy, and 35-year-old writer Harry. Will gentle giant James bowl his guests over with his Mexican street food and the grab the grand?
