For Masterchef's John Torode, British beef is his passion. His quest is for heritage beef and is shocked to discover that five breeds are on the critically endangered list. He heads to Scotland to meet a beef farmer dedicated to reviving the fortunes of the original, traditional Aberdeen Angus. Amongst the dishes he cooks in the Revival kitchen is a stupendous slow roast four bone rib of beef complete with Yorkshire puddings. If anything will persuade you to try rare breed beef it will be this incredible Sunday roast.Seafood supporter Valentine Warner wants to reverse the fortunes of British cockles and mussels. He discovers that the vast majority of our mussels are exported, and our cockle industry has shrunk to almost nothing. He is determined to remind us that these nutritious and plentiful fruits of the sea are fresh and available right on our doorstep. To encourage us to start buying them Valentine rustles up some delicious dishes in the Revival kitchen to show us how easy our shellfish is to cook.
