Jellies were once the extravagant food of kings. Henry VIII showed off with them, the Victorians raised them to a dazzling art form, a far cry from the lurid teatime horrors served up at children's parties where jelly has since languished. Simon Parkes celebrates our noble jelly-making past with historian Ivan Day, and looks to those raising it back onto its wobbling pedestal today: chef Heston Blumenthal, and "jellymongers" Bompas & Parr. And we ask food writer Jill Norman if jelly's savoury past could be set for a comeback. Producer: Rebecca Moore.
