The semi-finals continue as the celebrities are given their their most daunting challenge yet and are thrown into the world of mass catering on an impressive scale. Gonville and Caius is the fourth oldest college in Cambridge University, and 150 students, parents and fellows will be attending the prestigious end of term dinner. Working in pairs, the celebrities are responsible for providing a three course dinner of the finest standard to befit the surroundings and the occasion whilst working quickly to get their dishes out on time.

The greatest cooks in the world are able to show their emotion through their food - will the final six be able to do the same? For the one cook who does not make the grade, the competition will be over.
