Haasarud has a trick to give this drink the same look of drizzled chocolate sauce atop a classic ice cream sundae: she swirls some of the sauce along the inside of a tall glass and then pours in the cocktail, which is a mixture of coconut cream, pineapple juice, rum and chocolate. You'll see zigzags of chocolate through the glass—just watch out for a brain freeze. (For speedy blender cleanup after you're done, Haasarud has another smart idea: fill the pitcher with hot water until it's 1/4 full, add a few drops of dishwasher detergent, run the blender on high for a few seconds, then rinse with fresh hot water).
