Directions
-
Blend the Watermelon Mixture
Place the cubed watermelon, ice-cold water, and granulated sugar into a blender. Blend until smooth, using the smoothie setting if possible for the best results. You want the mixture to be silky-smooth without any chunks. -
Strain the Juice
Pour the watermelon juice through a fine-mesh sieve into a large pitcher or bowl to remove any pulp or seeds. Press the back of a spoon to help the juice pass through the strainer and into your pitcher. -
Add Citrus and Sweetener
Stir in the freshly squeezed lemon juice, lime juice, and agave nectar (or honey or maple syrup). Mix until well combined and taste for sweetness. Adjust with more sugar or sweetener if needed. -
Serve and Enjoy
Serve the Watermelon Lemonade over ice, garnishing with a slice of watermelon and fresh mint leaves. For extra flair, add a lemon or lime slice to the rim of the glass.

Storage/Reheating
-
Storing Leftovers: Store any leftover Watermelon Lemonade in a covered pitcher or airtight jar in the fridge for up to 2 days. Give it a good stir before serving, as natural separation can occur.

-
No Reheating: This beverage is best served cold, so there’s no need to reheat it. Just stir and pour over fresh ice if it’s been stored in the fridge for a while.
