Cookery competition with John Torode and Gregg Wallace. As the second week of heats continues, the next six amateur cooks try to prove to the judges that they have the potential to be the tenth MasterChef champion. Firstly, the contestants are asked to cook their calling card, a practiced dish that represents who they are as a cook and showcases their talent. They have just one hour to dazzle the judges with one plate of food that shows just what they can do. They then face the infamous invention test, choosing between two sealed boxes of ingredients. This time round, sweet ingredients include raspberries, filo pastry, brioche and rolled oats, while the savoury box contains chicken thighs, black pudding and roquefort. Two amateurs are sent home, and the four remaining cooks must cook an impressive menu for some special guests from the show's past. At the end of this, John and Gregg will select two cooks to take the next step in the competition and go through to the week's quarter-final.
