Original Rum Runner Cocktails Recipe

Original rum runner cocktails were created in the 1950s in Key West and are named after real “rum runners” or bootleggers. They would smuggle in rum during prohibition and would then hide away when tax collectors were making their rounds. Huh! Who knew?

Many moons ago I was a bartender working at an outdoor bar in downtown Charleston, and Long Island Iced Teas and Rum Runners were major sellers because they were so full of booze.

An original rum runner cocktail recipe calls for white rum, dark rum, banana liquor, blackberry liquor, orange juice, pineapple juice, and grenadine, but y’all know I had to zhoosh mine up a bit!  

My Watermelon cocktails contain a mixture of:

  • Pineapple Rum
  • Citron Rum
  • Silver Rum
  • Triple Sec or simple syrup
  • Melon liquor
  • Pineapple Juice
  • Freshly Juiced Watermelon

Items Needed to Make

You won’t need a lot, but you do need just a few tools to make these watermelon rum drinks:

  1. A seedless watermelon! Half of a seedless watermelon will yield nearly the exact amount of watermelon cubes you’ll need for 4-6 servings of this recipe.
  2. Something to blend up the fruit. I have a Ninja blender, but you could also use a food processor or personal blender too.
  3. A fine mesh strainer or sieve to strain out any seeds and watermelon chunks. This stainless sieve set is the best and comes in handy when making soups and custards too.
  4. A glass pitcher and set of cute glasses. You need glass pitchers and glasses here because the color of the fresh watermelon juice is a showstopper plus, with the blueberries floating around, these rum runners look like watermelon in a glass! This pitcher is cool because it adds an extra layer of filtration too, and I adore these cute mason jar mugs!
  5. Fresh or frozen blueberries and fresh mint, for garnish, ice, and friends!

How to Make Watermelon Juice

Making watermelon juice for watermelon rum drinks is so incredibly easy! It really is nothing more than cutting up the watermelon into chunks, blending it in a high-speed blender or food processor, and straining it into a large pitcher. That’s it!
