A hot cup of cocoa may not be the first beverage that comes to mind when you think Caribbean. But St. Lucia’s cocoa tea, a traditional spiced breakfast drink, may change that. Find the not-so-rich, bittersweet delight at the Castries open-air market, where food vendors steep bay leaves, cinnamon, nutmeg and grated cocoa sticks in huge pots all day long. Or buy the ingredients — plucked from the island and packaged in a calabash bowl by local peddlers — and brew this West Indies libation at home. You may never crave an umbrella drink again.
