<p>Dull? Boring? Plain? </p><p>Vanilla is a byword for something which is ordinary or standard. </p><p>In this programme Ruth Alexander finds the story of the popular spice is anything but normal. </p><p>Originating in Mexico it’s travelled the globe and taken over, and is now one of the most valuable commodities available. </p><p>It’s gone from being highly sought after and the height of luxury – even serving as an aphrodisiac for Mesoamericans and a European monarch - to ubiquitous and considered “regular”. </p><p>Despite its reputation there is still a lot to appreciate about this complex flavour, and fans in one ice cream parlour are keen to make sure it isn’t overlooked. </p><p>Presenter: Ruth Alexander </p><p>Producers: Nina Pullman and Hannah Bewley </p><p>(Image: A vanilla bean and flower.
