Poh Ling Yeow

This season's first Mystery Box sees fan favourite Poh Ling Yeow back in the MasterChef kitchen for one night only. Contestants must create a winning dish with little more than under bench staples.

Trevor, Sam and Tom make a Sticky Date and Toffee Pudding with Butterscotch Sauce and Almond Praline from a provided recipe.

Your favourites are back for another crack at the coveted MasterChef title. Up for grabs tonight is this season's only immunity pin and joining them all week is chef extraordinaire, Gordon Ramsay.

MasterChef alumni Poh, Callum and Reynold present the contestants with three dishes from their venues. Contestants must create a dish worthy of a place on the menu at any of these establishments.

Pressure Test Elimination - Tom, Poh, Chris and Julie had to make Croquembouche.

The winners of the Mystery Box and Invention Test face today's Immunity Challenge and MasterChef history is made when the judges choose who will cook against Young Chef of the Year, Max Sharrad.
