Why this watermelon agua fresca works
Great agua fresca is all about simplicity. Fresh fruit is blended until smooth, then lightly sweetened and diluted with cold water to create a drink that’s flavorful but not heavy. No complicated steps, no special equipment, and no artificial ingredients.
Watermelon’s high water content makes it ideal for this type of drink, resulting in a naturally hydrating beverage with a clean, smooth texture. A quick strain is optional, depending on whether you prefer a silky or slightly pulpy finish.
If you love fruit-based drinks with a creamy twist, Strawberry Smoothie offers a thicker, more indulgent alternative.
