Overview: The pressure is mounting as the country's best four amateurs continue in the seventh week of their incredible, culinary, competitive journey. The heat is on in more ways than one as judges John Torode and Gregg Wallace take the contestants to Thailand for the masterclass of a lifetime. The four are pushed to the limit as they are set an incredible series of challenges, beginning in the country's gastronomic capital, Chang Mai, amidst the bustling street food markets. The cooks are thrown in at the deep end for their first challenge - each is given a market stall to run and a popular dish to prepare, incorporating traditional Thai cooking techniques, which they must then sell to the hungry locals.
