Tips and Notes

  • When you add the sugar make sure the water is at room temperature so it can dissolve easy and fast. If you use cold water, dissolving sugar can be a hard task and you don’t want sugar grains in your fresca.
  • 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 strain the blend, always. If you prefer a more fruity texture, go ahead and add the mixture to the pitcher without straining.
  • 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. Or just replace refined sugar with any sweetener you prefer.
  • You can garnish your drink with diced watermelon, lime slices, or fresh mint leaves.


Can I make it sugar-free?

Absolutely. The drink will be less sweet but still, have a fruity delicious taste. Besides, ripe watermelons can have a strong sugary taste and you won’t miss the sugar at all.

Can you tell if a watermelon is ripe by smell?

Not really. Unlike cantaloupes, watermelons don’t have an open end where the vine was attached so if you sniff a watermelon I doubt you’ll be able to feel any smell.

Do I have to strain the watermelon mixture?

Not really. You can add it as it is and get the full benefit from the fruit’s fiber too.

Do I need to remove the watermelon seeds?

No, if you don’t want to, but in this case, we recommend straining the mixture if you don’t want annoying bites in your drink.

Can I spike this recipe?

Yes of course, for a grown-up drink, feel free to add a splash of your fav booze to the mix.

Can I make it ahead?

Yes. You can make this agua fresca de sandia up to 3 days ahead and store it in the fridge well covered to prevent it from absorbing other smells.

Can I freeze watermelon chunks?

Yes! and is actually a good idea because this way you can make this recipe whenever you crave it. To do so, place the chunks on a flat plate and freeze until firm, transfer the chunks to a bag and freeze for up to 4 months.
