Servings: 4

Ingredients
• 2 cups watermelon, seeded and cubed
• 1 cup pink grapefruit juice
• 4 tablespoons simple syrup
• Grapefruit-flavored sparkling water
• 8 lime slices
• 4 sprigs of fresh rosemary

Directions
1. In a small bowl, mash 1 cup of watermelon cubes with a muddler or fork until they have a coarse texture. Divide the purée between 4 tall glasses.
2. Add 1/4 of the grapefruit juice and 1 tablespoon of simple syrup to each glass. Mix with a spoon.
3. Fill each glass with grapefruit-flavored sparkling water. Divide the remaining watermelon cubes between each glass. Garnish with lime slices and a sprig of rosemary.

How to make simple syrup
Combine 1 cup of water and 1 cup of sugar in a small saucepan. Simmer over medium heat, stirring often, until the sugar is completely dissolved (about 3 to 5 minutes) and the mixture has thickened. The syrup can be stored in the fridge for at least two weeks.
