Ingredients
Scale
8 cups cubed seedless watermelon
4 cups cold water, plus more to adjust consistency
1/4 cup lime juice, freshly squeezed (about 2–3 limes)
1/4 cup erythritol or your preferred sugar-free sweetener (adjust to taste)
Pinch of salt
Fresh mint sprigs, for garnish (optional)
Lime wedges, for garnish (optional)
Ice cubes, for serving
Instructions
Prepare the Watermelon: Select a ripe, seedless watermelon. Cut into manageable pieces and then cube, removing any remaining seeds. Aim for roughly 8 cups of cubed watermelon.
Blend the Watermelon: Transfer the cubed watermelon to a high-powered blender. Add 2 cups of the cold water to the blender.
Blend Until Smooth: Blend the watermelon and water mixture until completely smooth (about 1-2 minutes).
Strain (Optional): For a smoother agua fresca, strain the watermelon puree through a fine-mesh sieve or cheesecloth-lined colander. Discard the pulp.
Combine: In a large bowl, add the remaining 2 cups of cold water and the freshly squeezed lime juice to the strained (or unstrained) watermelon puree.
Sweeten: Add the erythritol (or your preferred sugar-free sweetener) to the mixture. Start with 1/4 cup and stir well until dissolved. Taste and adjust sweetness as needed. Add a pinch of salt.
Adjust Consistency: If the agua fresca is too thick, add more cold water, a little at a time, until you reach your desired consistency.
Chill: Cover the bowl or transfer to a pitcher and refrigerate for at least 2 hours, or preferably longer, to chill thoroughly.
Prepare Glasses: Get your serving glasses ready. You can chill them in the freezer for a few minutes for an extra refreshing touch.
Add Ice: Fill each glass with ice cubes.
Pour and Garnish: Pour the chilled sugar-free watermelon agua fresca over the ice in each glass. Garnish with fresh mint sprigs and lime wedges, if desired.
Serve: Serve immediately and enjoy!
Notes
Sweetener Alternatives: Use stevia, monk fruit sweetener, or allulose instead of erythritol. Adjust the amount to taste.
Fruit Variations: Add cantaloupe, honeydew melon, strawberries, or cucumber to the blender.
Spice it Up: Add a small piece of jalapeño (seeds and membrane removed for milder flavor) to the blender.
Herbal Infusion: Add basil or rosemary sprigs to the blender.
Sparkling Agua Fresca: Top off with sparkling water or club soda before serving.
Make Ahead: Make it a day or two in advance and store in the refrigerator.
Freezing: Freeze in ice cube trays for a refreshing treat.
Watermelon Quality: Choose a watermelon that is heavy for its size, has a creamy yellow spot, and sounds hollow when you tap it.
Adjust Sweetness: Watermelon sweetness varies, so adjust the sweetener to your preference.
Lime Juice: Don’t skip the lime juice! Freshly squeezed is best.
