Jay Rayner hosts the culinary panel show. Professor Barry Smith, Rachel McCormack, Tim Hayward and Anna Jones join the virtual kitchen table to answer questions sent in by the audience via email and social media. This week, the panellists share roast potato recipes, discuss their disgust at certain eating noises and, together with the virtual audience, perform a sensory experiment which everyone can join in. All you need is some lightly butter toast and yeast extract. Producer: Darby Dorras Assistant Producer: Rosie Merotra A Somethin' Else production for BBC Radio 4
