The other two chefs take on a test set by Marcus, to prepare poached figs with honeycomb and flavoured cream.Then the four chefs have a chance to show the judges what they are all about, as they serve up their two-course signature dishes. They have one hour and 25 minutes to prepare a main and a dessert that highlight their personal style, and they will need to make an impression if they are to make it through to the quarter-final.
