Blend ingredients. In a high power blender, add chayote, cucumber, sugar, and 3 cups of water on medium setting for 30 – 60 seconds.
Strain and mix. Strain mixture through a fine-mesh sieve into a large pitcher. You may need to agitate the mixture, but avoid pushing through the pulp to keep the chayote juice light in consistency. Discard or compost the pulp. Mix in remaining 3 cups of water. Taste, and adjust sweetness, if desired.
Chill and enjoy. Chill in the refrigerator or serve over plenty of ice. I like to garnish my agua de chayote with thinly sliced chayote and cucumber.
A Note from Lola
HOW TO STORE AGUA FRESCA
Store agua fresca in an airtight container in the refrigerator for up to 2-3 days, ensuring it stays fresh and chilled. Ingredients tend to settle at the bottom, so remember to stir your agua fresca before serving.
ON SWEETENERS
You can add as much or as little sugar as you’d like to all of your aguas frescas, including this one. I also like to use honey, agave, or simple syrup (boil equal parts water and sugar until sugar is dissolved) in my agua fresca recipes.
ON TEXTURE
I have seen plenty of agua fresca recipes that say not to strain the ingredients. While I’m all about taking in all of the fiber and nutrients possible, agua fresca is meant to be light in texture – nowhere near a smoothie and not even as thick as a nectar. Therefore straining is essential in all of my recipes, except for my agua de sandía and agua de limón con sandía because watermelon is naturally watery and doesn’t require straining.
