Ainsley Harriott on Honey and Glynn Purnell on Cheese

In this fourth episode of the series, one of the UK's best known chefs, Ainsley Harriott, shows off his sweet side as he starts a campaign for the revival of British honey. With bees under threat from disease and a lack of awareness of our native honey production, Ainsley has to criss-cross the country to find out how we can all play our part in its revival. He also takes to the kitchen to show how honey can add its signature flavour to glazed duck breasts, a warm goats' cheese salad and a fabulous fig dessert.

Then its time for Michelin starred chef and Great British Menu favourite Glynn Purnell to ride to the rescue of British cheese. Cheap foreign imports, misleading labelling and a lack of public knowledge of the sheer variety of British cheeses available mean Glynn has his work cut out for him. But on his journey of discovery he meets some truly passionate cheese makers, samples some great tasting cheeses and shows off his own restaurant quality dishes.
