Summer is in full swing and the weather here in California has been just beautiful. We’ve had a few insanely hot days, but for the most part it’s been moderate temperatures, cool breezes and plenty of blue sunny skies. I’ve been doing a lot of outdoor entertaining to fully take advantage of the season, and one of my favorite things to do is invite family and friends over for appetizers and drinks, including this watermelon agua fresca.

How Do You Make Watermelon Agua Fresca?

This drink is a simple combination of fresh watermelon, sugar, lime juice and water that gets blended together for a sweet and refreshing complement to the bold flavors of the dip. The first step in making the agua fresca is to blend together watermelon, lime juice and sugar. The watermelon mixture gets strained and mixed with water and you’ve got agua fresca! I like to make my watermelon agua fresca extra party-worthy by serving it up with fun garnishes, like sugar crusted glass rims, fresh mint sprigs and lime slices. You can even garnish with small wedges of watermelon if you like.

Tips for Agua Fresca

  • You can make this drink with other varieties of fresh fruit, including strawberries, mango and pineapple.
  • Look for a super ripe watermelon for the best flavor. If your watermelon isn’t as sweet as you’d like, you can add more sugar, 1 tablespoon at a time, until you reach the desired sweetness level.
  • If you prefer a tart drink, you can double the amount of lime juice.

Summer entertaining doesn’t have to be complicated or time consuming. Your guests will be thrilled with this hearty and refreshing combination of savory dip and sweet cool drinks, and you’ll be happy to spend time with your family and friends instead of spending hours in the kitchen!
