Nothing cools me down on a scorching day quite like a big icy glass of watermelon agua fresca. Sweet, tangy, and full of pure fruit flavor, this vibrant drink is a summer essential in my kitchen. I make it every time fresh watermelon appears at the markets, and it always disappears within minutes.
The first time I served this at a barbecue, the pitcher was empty before I finished making the sides. Everyone from my youngest niece to my dad raved about how bright and thirst-quenching it was.
Ingredients
- Watermelon: ripe and seedless watermelon gives you that juicy sweet base look for heavy melons with a uniform shape and a large yellow spot
- Granulated sugar: balances the flavor and brings out the natural sweetness opt for organic if possible
- Lime juice: adds tang and lifts the melon flavor choose limes that are heavy for their size and have shiny skin
- Salt: brightens and intensifies all the flavors use a pinch of fine sea salt
- Ice: chills the drink and adds texture
- Chamoy: optional but amazing for rimming glasses with a tangy spicy kick look for quality brands in Mexican markets
Step-by-Step Instructions
- Blend the Base:
- Add fresh watermelon cubes lime juice salt and sugar to your blender Process on high until the mixture is completely smooth and frothy
- Strain for Smoothness:
- Pour the blended mixture through a fine mesh sieve or cheesecloth into a pitcher Press gently with a spoon to extract more liquid leaving pulp behind for a silky texture
- Prepare Glasses:
- If using chamoy or chili powder for the rim dip the glasses gently into the liquid then into a plate of your chosen seasoning for an extra touch
- Serve Over Ice:
- Fill glasses with plenty of ice Pour in the strained agua fresca right up to the rim Garnish as you like and enjoy immediately

Out of all the agua fresca varieties I make watermelon is my absolute favorite for its scent and color I remember my daughter asking to help me blend it as soon as she saw that deep pink hue in the blender That first kitchen mess was totally worth the memory
Storage Tips
Keep your watermelon agua fresca fresh by storing it in a tightly sealed pitcher or container in the fridge It will maintain its flavor for up to five days Stir well before serving as some separation is natural Do not leave it out in the sun or at room temperature for hours as this can change the flavor
Ingredient Substitutions
If you do not have lime juice try lemon juice for a similar bright kick Honey or agave can replace sugar for a different sweetness Use frozen watermelon cubes if you want an extra icy drink or need to use up leftover melon

Serving Suggestions
Pour this agua fresca into tall glasses with lots of ice and serve with a slice of lime or a sprig of mint I love setting out a tray with chamoy and chili powder for guests to rim their glasses It pairs especially well with light summer meals like grilled chicken tacos or fresh salsa and chips
