Cool off in the summer heat with this watermelon basil cocktail that takes only five minutes to prepare. Fresh lime juice and chunks of frozen watermelon infuse the alcohol with a sweet, refreshing flavor. Serve this drink with a lime wedge, basil sprig or watermelon slice for an extra summery touch.
- white rum
- Grand Marnier – You can substitute with triple sec if you are looking for a cheaper option.
- lime juice – Freshly squeezed.
- simple syrup – A mixture of equal parts water and sugar heated together until the sugar is dissolved.
- fresh basil leaves – Regular sweet basil. I added just enough so that you can taste the basil but it’s not overpowering. You can start with a few large leaves and add more to taste.
- frozen watermelon chunks – Can either freeze your own cubed watermelon or buy pre-frozen chunks. Try to use the most red-colored chunks so that your drink has a nice, vibrant color to it.
- ice cubes
If you have a watermelon in the fridge, slice the fruit into cubes, lay them on a sheet tray and throw them in the freezer. Frozen watermelon makes your drink extra cold and blendable and creates a slushy-like texture that’s perfect for hot, humid days.
This recipe features white rum. You can try out coconut-flavored white rum which has a subtly sweet flavor and hints of coconut and vanilla. Aged white rum has additional tropical fruit notes that vary. This watermelon basil cocktail will be a tropical treat for rum connoisseurs.
Likewise, Grand Marnier offers a complex orange and toffee flavor with hints of oak and vanilla.
While lime juice adds some citrus bite, basil complements the drink with a slight sweetness and earthiness. You can sweeten the drink to your taste with simple syrup, which is essentially liquid sugar, or leave it out entirely if you prefer.
