麻豆约拍

The week's six best chefs return for the quarter-finals. With just two places in the semi-finals up for grabs, this is where the battle really begins.

First the chefs must show Michel and Monica they have what it takes with a dish of their own invention. Choosing from a range of ingredients, including bone marrow, kid goat, oysters and whelks, mangoes, white chocolate and dates, they have an hour to cook a sweet or savoury dish good enough to propel them into the next round. Only the best will do because after this first challenge Monica and Michel will send two chefs home.

The best four chefs then face their most nerve-racking test to date. They must showcase their skills to three of the UK's toughest restaurant critics - William Sitwell, Tracey MacLeod and Jay Rayner. With only an hour and a quarter, the remaining chefs must deliver a jaw-dropping two-course menu - their MasterChef future depends on it.

Only the two most talented chefs will go through to the semi-finals and stand a chance of becoming this year's Professional MasterChef.
