I have been obsessed with making these lately. You could do so many different varieties! It is also a great way to use up those cantaloupes and watermelons you buy that aren't perfectly sweet.
1/2 mini watermelon
juice of 1 lime
juice of 1 lemon
3 Tbsp Agave nectar
2 Tbsp mint leaves
2 Tbsp basil leaves
2 cups of water
sparkling water - I used lime flavored La Croix
Work in 2 batches. Blend half the melon, herbs, agave, lime and lemon juice and 1 cup of water.
Strain through a fine mesh seive or cheese cloth. Toss the pulp. Repeat blend the second batch and strain.
Fill a glass of ice 3/4 the way with juice and then the rest of the glass with sparkling water. (You could also add some rum or vodka for a refreshing cocktail!)
