Jay Rayner and the panel are at the Institute of Making at University College London. Joining Jay to answer questions from an audience of keen home cooks are chefs and food writers Melissa Thompson, Jocky Petrie, Tim Anderson and, on home turf, materials expert Dr Zoe Laughlin.

The panel discuss the trials and tribulations of fermentation at home, the Peruvian delicacy involving bacteria from feet, and whether Jocky's knife collection is excessive. Later in the show, Zoe puts the noisiest of foods to the test with her very own UCL food 'choir' to assess which lunches make the loudest crunches.
