Jay Rayner is back for a new series. This week he's joined by culinary experts Andi Oliver, Tim Hayward, Fliss Freeborn and food historian Dr Annie Gray. Jay and the panel are in Tring, Hertfordshire, an area famous for flour production. Archeobotanist and organic farmer John Letts explains what he thinks makes medieval heritage grains superior to ‘commodity’ grains, while the panel offer advice on how to use flour to its full potential. Tring is also famous for the Natural History Museum and its collection of stuffed mammals, birds and insects, allowing the panel to ponder the most exotic thing they have ever stuffed to eat. The debate reveals some surprising answers - not for the faint hearted!
