TV chef Rick Stein sets off across Spain in a camper van in search of what the Spanish call 'culinary duende' - a soulful and meaningful gastronomic experience. Taking in a wide range of Spanish regions - Catalonia, Castilla-La Mancha and Andalusia to name but a few - Stein explores the local delicacies of each in a bid to reach his Iberian epiphany. As well as sampling the dishes themselves, Stein takes a look into how their crucial ingredients are produced, visiting vineyards, garlic farms and Cabrales cheese caves to observe first hand their techniques of production. Along the way Stein tries out Asturian fabada, Basque tapas and the prawns of Palamós; which will provide him with the elusive culinary duende?
