To mark British Pie Week, Countryfile is in the birthplace of the pork pie – Melton Mowbray in Leicestershire. Margherita Taylor visits the cathedral of pies, home of the British Pie Awards, to find out what makes for pie perfection. Matt Baker discovers Melton Mowbray's other mouthwatering delight, stilton cheese, and Matt and Margherita both put their tastebuds to the test as they try the art of pairing food and beer. Adam is on the trail of Somerset strawberries grown all year round, and who will be top dog when comedians Tim Vine and Kiri Pritchard-McLean go head-to-head in a special Red Nose sheepdog trial for Comic Relief?
