I sliced fruit southward through the Windward Islands, looking out the galley porthole at some of the most idyllic anchorages I'll ever hope to see. At Petit Nevis, just south of Bequia, we capped off a midday snorkel with arroz con pollo-and fruit salad. In the private-island playground of Mustique, we substituted barracuda-filleted by the clerk at the dockside fish market-into our spicy shrimp kebob recipe. For a day trip to Baliceaux, northeast of Mustique, we prepared black bean, corn, and avocado salsa, sans avocado, which had yet to ripen. As the latitude diminished, so did our adherence to recipes. By the time we reached the Tobago Cays, wayward ingredients were colliding into tasty, if not cholesterol-free, creations like peanut butter, bacon, and banana bread sandwiches.
