Ingredients
- 1 cup diced watermelon
- 2 tbsp fresh lime juice
- 2 cups cold water
- 1 tbsp honey
- 5 fresh mint leaves
- 1 cup ice cubes
- 1/4 tsp sea salt
- 1 cup sparkling water
- 1 tsp grated ginger
- 1 tbsp agave syrup
Equipments
- Blender
- Fine mesh strainer
- Measuring cups and spoons
- Tall serving glasses
- Wooden spoon or muddler
Step-by-Step Instructions
Step 1: Blend the Watermelon Base
Add the diced watermelon, lime juice, grated ginger, honey, and 1 cup of cold water to your blender. Blend on high for 30 to 45 seconds until completely smooth. This forms the flavor core of your Watermelon Lime Cooler, so make sure everything is fully broken down and no chunks remain.
Step 2: Strain and Mix in Fresh Flavor
Pour the blended mixture through a fine mesh strainer into a pitcher to remove any pulp for a smoother sip. Stir in the remaining cup of cold water, sea salt, and agave syrup. Gently muddle the mint leaves in your hand or with a muddler before dropping them into the pitcher to release their aroma without turning the drink bitter.
Step 3: Add Sparkling Water and Serve Over Ice
Fill your serving glasses with ice cubes, then pour the watermelon mixture over the top, leaving a little room at the rim. Top each glass with sparkling water for a light fizz and give it one gentle stir. Serve immediately so this healthy watermelon lime cooler recipe stays cold, bubbly, and refreshing from the first sip to the last.
Pro Tips
- Use seedless watermelon to save time and avoid straining out extra seeds.
- Chill your watermelon in the fridge beforehand so you can skip extra ice and avoid a watered-down drink.
- Taste before adding all the sweetener since watermelon ripeness can vary a lot.
- Add the sparkling water last and right before serving so the drink stays fizzy.
- Freeze small watermelon cubes as ice cubes for a stronger flavor punch as they melt.
