Agua Fresca is a traditional Latin American drink made of fruit, water, and a sweetener. It reminds me of the sweet and fruity drinks I had as a kid, only agua fresas are made with the real thing!
With my agua fresca, I skipped the sweetener and used mint to add a hint a sweetness instead. You can use the sweetener of your choice, to taste if yours still tastes too tart for you.
You can try this with different fruits and herbs. The pineapple mint agua fresca would also be a great base for a grown-up rum cocktail.
