The semi-finals continue on MasterChef: The Professionals. Just six incredible chefs are left, split into two groups. The first three will have their wits tested across two challenges that will demand laser focus and determination. High risks will bring high rewards, as the best on the day will continue on their journey to finals week.To start, the three chefs head into central London where they will manage a lunch service like no other - in the kitchen of a restaurant recently ranked as one of the top 50 in the world - Ikoyi. Founder and chef Jeremy Chan is one of the country's most exciting culinary stars, and nothing gets past him unless it meets the restaurant's two-Michelin-star standard. Tasked with cooking a dish from his staggering 18-course tasting menu, each of the three contenders will need their wits about them if they hope to impress.Next, it's back to the MasterChef kitchen, where the brief is simple – deliver two dishes worthy of a place in finals week. One main course and one dessert in one hour and 45 minutes that blow the water out of the competition and leave Marcus and Monica with no option but to put them through. It's time to throw caution to the wind and leave nothing on the table, as nobody wants to miss out on the adventure that awaits.The toughest judging so far will see one chef bite the dust and the other two progress to finals week as the race for the MasterChef: The Professionals title reaches fever pitch.
