Hoist the main sail and let the favourable trade winds transport you to an island paradise where cocoa comes in copious quantities, vanilla is always vicinal, and the sweet, spicy scent of overproof rum is rarely absent. Feel as your body is gently warmed by the tropical twilight sun – though that could be the rum – and let this Caribbean chocolate rum and raisin cake banish the cold and dark…if only for a  short while.
