In the second heat of the week, six of the UK's most determined chefs make the journey to the MasterChef kitchen ready to fight for the coveted title. Ahead of them are two challenges designed to challenge their ability in the kitchen - from taste and technical flair to creativity and ability to work under pressure. These chefs' every move will be watched over by Monica, Marcus and Gregg. At the end of the heat, only the three best chefs will go through to the quarter-final.
