Ingredients to make aguas frescas:
cold water (still or sparkling, as you prefer)
lime, mint and basil syrup
ice cubes to serve
Blend watermelon in a mixer and strain the puree to remove seeds. Combine in a jug watermelon juice, cold water to taste, syrup and ice cubes. Garnish with some mint leaves or lime slices and serve.
A few tips: if you have patience and want to remove manually all the seeds, you can avoid straining the watermelon puree, leaving more substance to drink. You can replace watermelon with any fruit you like, I tried it with peaches and it was just as good! I would suggest adding cucumber, or maybe a few ice cubes made with cucumber juice as I saw a few nights ago on tv.. genious! I think would be fantastic and refreshing!
