Jam. Think sticky apricot and saccharine strawberry? Think again. Our British love affair with jam goes back to the sweet-toothed 17th century. But now our interest seems to be waning. Shop sales of jam are down amid concerns over the amount of sugar we consume. And anyway, who has time for preserving pans and pretty pots?

But there is another way. In fact there are many. In this programme, 'queen of preserving' and author of 'Salt Sugar Smoke, how to preserve fruit, vegetables and fish' Diana Henry, meets the people thinking differently about jam.

She finds out how to use some of this year's gluts of fruit with Mary Longford, the woman behind Absolute Preserves in Somerset, discovers a beloved but forgotten fruit with gardener and food writer Mark Diacono; And speaks to Fraser Doherty, the man whose healthier jams have made him an international icon with an MBE to boot.

With advice from American preserves blogger for 'Food in Jars' Marisa McClellan, Diana hosts a canning (or jamming) party and explores culinary traditions of jam making from Scandinavia, Ukraine and beyond with food writers Olia Hercules and Camilla Plum. Recipes from around Europe which won't require shiny new kit.

Diana Henry wants you to rise up, and make jam.
