Jay Rayner hosts a culinary panel show packed full of tasty titbits. This week he welcomes Sophie Wright, Tim Anderson, Sumayya Usmani and Professor Barry Smith to answer questions from a virtual audience. After all that rich food over the festive period, you may be in need of a palette cleanser. Professor Barry Smith leads the team in an experiment to test why mackerel and horseradish work so well together. Beyond the science, the panellists cosy on down to discuss hot drinks with some spice and the unexpectedly divisive subject of slow cooking.
