Great British Food Revival: Potatoes and Pork

A series in which ten of the BBC's best-known chefs and cooks are on a mission to popularise traditional British produce. Each chef champions a produce that is close to their heart but is in danger of being lost forever. They also demonstrate how to cook fabulous meals featuring these ingredients. In this episode, greengrocer cum MasterChef host Gregg Wallace makes a case for the revival of the humble spud. He tracks down some heritage varieties that are full of flavour, and whistles up three fabulous dishes including a definitive shepherd's pie and his own favourite, dauphinoise potatoes. Clarissa Dickson Wright meets some of the hardworking farmers battling to preserve our rare breed porkers and lets us in on some of her cooking secrets, including how to get perfect crackling on your Sunday roast
