Summer is right around the corner – time for patios and picnics, pools and potlucks! What better way to beat the heat than a refreshing and delicious Agua Fresca.

What is an Agua Fresca? Agua Fresca is a fruit juice made of fresh fruit blended with water, lime juice, and sugar. It’s a popular drink in Mexico and Central America. While it can be made with many types of fruit, we’re using watermelon in our recipe.

Something about the sweet taste of watermelon mixed with lime juice just seems like the perfect combination. Make this drink as sweet as you like or rely more on the watermelon and lime flavors. Blend up a batch, serve over ice, and melt away that heat and humidity!

How To Make Watermelon Agua Fresca

  1. Scoop out the inside of your 8-pound watermelon. Place the fruit into a large capacity blender. Add 2 cups of water, granulated sugar, and lime juice. Blend until smooth.
  2. Continue to blend in more water and sugar until you get the consistency and taste you prefer. Strain the watermelon juice through a fine mesh sieve or colander into a large pitcher.
  3. If you like pulp, leave as is. If you prefer a juice with less pulp, strain the mixture 2-3 more times or as needed until you reach the smoothness you desire.
  4. Chill the agua fresca in the refrigerator until ready to serve. Pour over ice and garnish with lime wedges and thinly sliced watermelon wedges. Cheers!

Tips and Variations:

  • Some other fruits to make frescas with:
    • Pineapple
    • Strawberries 
    • Cantaloupe 
    • Honeydew
    • Cucumber (add some mint!)
    • Guava
  • Strain the juice multiple times to remove pulp, or strain once if you don’t mind a touch of pulp in your drink.
  • A garnish of mint or basil adds an interesting flavor to the juice.
  • Add ice to make a more slushy like drink.
  • We don’t recommend using berries like blackberries, raspberries, or blueberries as they are too seedy and are hard to strain the seeds out.
  • Start with less sugar. You can always add more.
  • Depending on how juicy your watermelon is, you may want to start with less water and only add more if needed.
