Rebecca Stott is on a quest for a decent-tasting apple. Along the way she discovers a revival of interest in wonderful heritage varieties: the rough-textured russets like Ashmead's Kernel, the rich, aromatic Saltcote Pippin or the sharp tanginess of the Alfriston.

Rebecca asks why - given the UK has an impressive two and a half thousand varieties of apple - we can only buy four or five in the average supermarket.
