Agua de sandía con limón is the most refreshing memory of my Mexican summers, watermelon and lime blended into something so cool it felt like relief in a glass. There was always a pitcher of some agua fresca going, and on the hottest days this was the one we fought over. It is barely a recipe, just ripe fruit and a squeeze of lime, but it captures summer better than almost anything I know. Here in Arizona, where summer means business, I keep a pitcher in the fridge all season. Blend it, pour it over plenty of ice, and you will see what I mean.A refreshing and easy Mexican agua fresca made with juicy watermelon, fresh lime juice, and a touch of sugar. Perfect for cooling off on hot summer days, ready in minutes with just a blender
Blend: In a blender, combine the watermelon chunks, lime juice from 5 limes, sugar, and 2 cups of cold water. Blend until smooth.
Strain (optional): If desired, strain the mixture through a fine mesh sieve to remove pulp.
Dilute & Chill: Pour the blended juice into a large pitcher. Add 2 to 3 more cups of cold water, depending on how strong or light you like your agua fresca. Stir well and taste—adjust sweetness if needed.
Serve: Add ice and lime slices to the pitcher or individual glasses. Serve chilled and enjoy!
