Additions And Variations

Here are some tasty additions and variations to customize your watermelon rum drink:

Additions

  • Fresh Mint or Basil: Muddle a few leaves for a herbal twist.
  • Coconut Water: Add a splash for a tropical, hydrating touch.
  • Chili or Tajín Rim: Coat the rim of the glass for a spicy kick.
  • Honey or Agave Syrup: Sweeten the drink slightly if the watermelon isn’t sweet enough.
  • Club Soda: Top with soda for a fizzy version.

Variations

  • Frozen Watermelon Rum Slush: Blend all ingredients with ice until slushy.
  • Watermelon Mojito: Add mint, swap orange liqueur for a splash of soda.
  • Watermelon Rum Punch: Mix in pineapple juice and a bit of grenadine for a party-sized punch.
  • Mocktail Version: Skip the rum and orange liqueur, and add more lime juice and soda.
  • Berry Blend: Add a handful of strawberries or raspberries for extra flavor.

Storage And Shelf Life

Watermelon rum drink is best enjoyed fresh, as the flavors and texture can change over time. If you need to store leftovers, keep them in an airtight container in the refrigerator for up to 24 hours.

The watermelon may start to lose its freshness and become watery. However, if you’ve made a large batch, it’s best to store the drink without the ice and garnish, as these can dilute the flavors.

For longer storage, you can freeze the mixture (without alcohol) and blend it again before serving.
