The perfect pesto. The best bouillabaisse. The purest paella. A river of gold flows through western Italy, southern France and eastern Spain. It's the olive oil that links three great cuisines, along with a love of garlic, anchovies, peppers, fresh herbs and seasonal vegetables. In stories and recipes, and beautiful location photography, Coastline explores the legacy of the ancient Greeks, the Romans, the Arabs and the Vikings, who left the gift of a 'cuisine of the sun' flavoured with generosity and conviviality.
