How to make watermelon agua fresca

Blend watermelon, water and maple syrup in a blender.

Add lemon, stir and taste it. If you like it, you are done, if not, adjust to your liking.

Straining watermelon agua fresca will get rid of most of the pulp as well as any seeds that have not been blended. This step is optional, but I would recommend doing so. It will give you a closer taste of water rather than a juice.

Make sure to chill it well in the fridge before serving.

Useful tips

  • The sweeter the watermelon, the tastier the agua fresca. Also, you might not need to add any sweetener at all.
  • I used maple syrup as a sweetener to make it refined sugar-free. You can use any sweetener you like. If you add honey, I recommend doing so after the first tasting and make sure to blend it well, as honey does not melt well in cold water.
  • You can add more water if you like this flavored water lighter in taste. You will also get more out of it.
  • To achieve the best flavor, I recommend using bottled water.
  • If you don’t have time for chilling, use ice cubes (preferably the large ones, so they won’t dilute the water too much)!
