Add watermelon to a blender, pour two cups of water, and blend until smooth.
Strain watermelon mixture into a large pitcher.
Add lime juice and the remaining water.
Add sugar to taste mixing thoroughly to dissolve it before adding more.
Serve in glasses over crushed ice or store the pitcher in the fridge for a couple of hours before serving.
When you add the sugar make sure the water is at room temperature so it can dissolve easily and fast.
Ad as much water as is needed to make the fresca actually a light drink and not a slushie or a smoothie drink.
I prefer my frescas to be super smooth and don’t have fruit bites so I always strain the mixture.
If you want to make this watermelon fresca ahead of time, do not add ice to the pitcher or you will end with a bland drink after the ice has melted. Place the pitcher in the fridge instead and only add ice right before serving.
Don’t sure about adding sugar? No worries, this agua de sandía is delicious as it is. Omit the sugar and you still will have a refreshing and delicious drink.
You can garnish your drink with diced watermelon, lime slices, or fresh mint leaves.
