In a blender, add fresh fruit, water and lime juice. Blend on smoothie mode.
Add sweetener to taste. You may want to try it before adding sweetener and see if the natural sweetness is enough. If your drink needs sweetener, start with just a teaspoon and go up to a tablespoon if needed.
Pour into cups with ice and serve immediately.
Notes
Mix your favorite flavors. My personal favorites are pineapple with mint and watermelon with mint and extra lime. Make a pitcher drink by doubling this recipe. I love to make several flavors to serve at a party or gathering.Leaving the pulp in this drink is healthy and tasty. It is not necessary to strain Agua Fresca as the natural fiber is a key element of what makes this drink special. If you prefer to strain your drink before enjoying, use a fine mesh sieve to do so.
