Watermelon Limeade Cocktail
Ingredients
Monk Fruit Simple Syrup
- 1 cup water
- 1 cup monk fruit sweetener (you can substitute regular sugar if you prefer; avoid substituting with coconut sugar)
Watermelon Limeade Cocktail
- 2 cups watermelon, cut into cubes (about 1/4 of a large watermelon)
- 1 cup vodka (a clean, neutral vodka works well)
- 1/2 cup fresh lime juice
- Mint sprigs, for garnish
Instructions
Make the Monk Fruit Simple Syrup
- Combine the water and monk fruit sweetener in a small saucepan. Whisk together to combine.
- Bring the mixture to a gentle boil, whisking until the sweetener is fully dissolved. Once it reaches a boil, remove the pan from heat and allow the syrup to cool to room temperature.
- Transfer the cooled syrup to a clean jar or bottle. Set aside 1/2 cup to use in the cocktail and reserve the remainder for future batches or other beverages.
Blend and Serve
- In a blender, combine the watermelon cubes, vodka, fresh lime juice, and 1/2 cup of the cooled monk fruit simple syrup.
- Blend until completely smooth. Taste and adjust sweetness—if you prefer a sweeter drink, add a tablespoon or two more syrup and blend again. If it’s too sweet, add a splash more lime or a bit of cold water to balance.
- Pour the blended mixture through a fine-mesh strainer if you prefer a smoother texture without pulp, or serve unstrained for a more rustic, pulpy drink.
- Serve over ice and garnish with fresh mint. For a festive presentation, serve in chilled glasses with a lime wheel or a small skewer of watermelon cubes.
- Note: you will likely have about 1/2 cup of leftover simple syrup. Keep it refrigerated—it’s perfect for making another batch or sweetening iced tea, sparkling water, or mocktails.
Tips and Variations: For a mocktail, omit the vodka and top each glass with sparkling water or club soda for fizz. To make a frozen version, freeze the watermelon cubes and blend them with the other ingredients until slushy. If you want a lighter cocktail, reduce the vodka to 3/4 cup or add more ice. Fresh lime juice is key for bright acidity—bottled lime juice tends to be flatter in flavor.
Storage: Store any leftover syrup in a sealed container in the refrigerator. The syrup can also be used to sweeten other summer drinks or desserts.
