Jay Rayner hosts the culinary panel show packed full of tasty titbits. Joining him this week are Tim Anderson, Sue Lawrence, Shelina Permalloo and Professor Barry Smith to help answer questions from hungry listeners. This week in a scientific special, the panel are quizzed on their favourite kitchen gadgets, as well as going through nearly every possible configuration of tofu imaginable. They are joined by food science expert and author Harold McGee, who uncovers the chemistry of cooking. Sensory expert Professor Barry Smith leads us in a tantalising tastebud experiment - if you’d like to join in at home, you’ll need some Szechuan peppercorns handy (and not be averse to eating them raw…) Producer: Daniel Cocker Assistant Producer: Bethany Hocken A Somethin' Else production for BBC Radio 4
