Nothing beats eating slices of refreshing watermelon on a hot summer day.  Packed with vitamins C and A, watermelon is a quintessential picnic and potluck food and always a favorite especially children.

I remember a time our family enjoyed a picnic along the shores of Lake Washington at Matthew’s Beach.  Eli had just turned three years old and I brought a whole watermelon expecting to take at least half of it home.  But the weather that day had been unusually hot.  When I cut into our watermelon I watched Eli eat slice after slice and was both amazed and concerned by his appetite.  On one hand I thought it was cute watching the red juices drip down his chin, despite the pink stains on his white t-shirt.  I wondered if eating too much watermelon was a bad thing, but I rationalized with myself that he was only eating water with a little bit of fiber.

With a bulging little belly full of fruit and a pile of thick green rind slices next to him, Eli impressively put down a half watermelon all by himself.  I’ll always remember that day!

I know my Eli isn’t the only kid who loves watermelon and today I have a recipe using this kid-favorite fruit.  An elevated adaptation of a summer classic drink, today I’m sharing with you a fantastic, thirst quenching recipe for Watermelon Mint Lemonade.  Sweetened with agave syrup, this drink is the perfect balance between sweet and tart with a refreshing subtle flavor of mint. 

This is the perfect recipe to serve guests during the Fourth of July holiday weekend coming up.  Kids will love this all-natural vibrant summer drink and parents will appreciate this new fun and delicious way to use leftover watermelon, which can take up a lot of space in the refrigerator.

    Could i substitute the agave syrup for anything else?

      I too would rather avoid using Agave Syrup (Fructose) as a sweetener. I like to use Stevia as a 100% natural, zero calorie sweetener for lemonade and coffee type drinks. There are many brands of blended Stevia based products but I favor using pure Stevia extract. Sprouts, Trader Joes and Amazon offers pure Stevia for sale. You only need to use a very small amount of Stevia for a single glass (about 1/64 of a teaspoon). Just add a little Stevia, taste, and then add more to your liking.

      In regards to using something other than Agave I usually use honey. It is really good in lemonade and does not have the weird after taste I feel Stevia has. I would experiment with the ratio to use though depending on how sweet you like your lemonade. I would at first try a 1:1 ration substitution then move up from there. I hope this helps out anybody else wondering this same question.
