Ruth Sanderson meets a truffle farmer on the Isle of Bute, just off the west coast of southern Scotland. Truffle expert Dr Paul Thomas is planting the first truffle plantation on the island, in joint venture with sheep farmer Ian Dickson. Ruth helps to plant hazel trees which have been inoculated with the truffle fungus, and hears how they hope to reap a profitable harvest within at least six years.
