To prepare a Tropical Island Baked Beans recipe, first you need to prepare the ingredients for the recipe. First, you'll need: 1 pound (240 g) dried beans, 1 cup (250 ml) water, and 1 tablespoon (2.5 tsp) kosher salt. You can also use frozen beans if you don't have fresh beans. Place the beans in the bottom of an 8x8x2 inch baking dish. Pour the ketchup, Worcestershire sauce, chili powder, cumin, salt and pepper into the mixture and stir to combine. Cover the dish with plastic wrap and refrigerate overnight. In the morning, preheat the oven to 375 degrees F (190 degrees C) and bake for 20 minutes or until the top is brown and bubbly. Serve with sour cream and guacamole.
