Ingredients
  

Homemade Watermelon Juice

  • 1 ripe seedless watermelon You can use a regular ripe watermelon too, just be sure to remove the seeds before blending!

Watermelon Rum Cocktail

  • 2/3 cup watermelon juice
  • 1/2 oz simple syrup homemade or store-bought
  • 1 tsp fresh lime juice
  • 3 oz white rum You can also use silver rum or even a coconut rum. Just be sure to use a light rum, as dark rum will change the flavor of the finished cocktail
  • little watermelon wedges for garnish, optional
  • ice cubes for prepping the cocktail

Watermelon Mocktail

  • 2/3 cup watermelon juice
  • 1/2 oz simple syrup homemade or store-bought. Since there isn’t any alcohol to cut through the sweetness of this drink, I would recommend starting with half the amount of simple syrup, tasting and adjusting if needed.
  • 1 tsp fresh lime juice
  • little watermelon wedges for garnish, optional
  • ice cubes for prepping the mocktail

Instructions
 

To make homemade watermelon juice

  • Chop your watermelon into chunks and place in an upright blender(be sure to set a couple pieces aside to use for a garnish!) and blend on high speed until completely liquified. 
  • Pour the watermelon juice through a fine mesh strainer, discard any pulp or seeds, and set the finished juice aside until ready to use. 

To make a watermelon rum cocktail

  • Place a few ice cubes into a cocktail shaker, followed by the watermelon juice, lime juice, simple syrup, and rum. Cover tightly and shake roughly for about 30 seconds.
  • Strain the finished cocktail mixture into two glasses of choice. Garnish with a little watermelon wedge on the rim of each glass and serve immediately.
  • Enjoy!

Notes

Since you don’t need a lot of watermelon juice for this recipe, you can blend half or even a quarter of your watermelon and save the rest for fresh eating! Fresh watermelon juice can be stored in the fridge for up to 3 days, but is best consumed within 24 hours. Also, watermelon juice should stay chilled and should not be left sitting at room temperature for longer than 2 hours. 
Feel free to add more simple syrup to this cocktail if it isn’t sweet enough for you. You can also sweeten this cocktail with honey or agave nectar instead of simple syrup.
You can find my easy, homemade simple syrup recipe HERE! Simple syrup can be found and bought at most local grocery stores.
