Episode 18

The last semi-final challenge is a celebration of MasterChef's surprise musical fame. Ten years after MasterChef judges John Torode and Gregg Wallace were sampled on the hit single Buttery Biscuit Bass, this episode marks this momentous achievement by returning the favour. The final six contestants must prepare a dish that is inspired by that song and one of over 20 different food references within it. Savoury or sweet, it's up to the contestants to interpret the brief, and the dish must impress the judges enough to secure a place in finals week. At the end of this challenge, one contestant's MasterChef dreams will be dashed, while the other five move closer to becoming MasterChef champion.
