It is the final heats week and six new ambitious chefs set out to prove they have what it takes to win the coveted title. The first three chefs must make an artichoke barigoule. This rustic dish from the south of France should be a breeze, but even the humble artichoke can be catastrophic for a terrified chef. The remaining three chefs must dish up a hot lamb sandwich with a pea and mint salsa. The simplicity of the dish belies the depth of skill on show and the excellence the judges will be keenly watching out for. The six chefs then have one last chance to show the judges they are top calibre when they cook their signature dish. They must deliver on presentation, technique and flavour if they want to secure their future in the competition, because when it is all over, the three weakest chefs will be sent home. Only the three most talented chefs win a place in the last quarter-final and continue in their cooking battle for the prestigious Professional MasterChef title.
