Overview: Tebay Services prepares to celebrate its 50th birthday, and chef Jim is challenged to come up with a contemporary version of a popular dish from the farm shop's 1970s roots. On the service station's High Chapel Farm, a tree-planting scheme is underway. Farm shop buyers Alex Evans and Jane Karlicek and butcher Dave Morland work with the Woodland Trust, in an effort to bring more wildlife into the area.
