Watermelon Agua Fresca

Your rating
Two glasses of watermelon agua fresca with a pitcher and a jar of Saltivate Watermelon

This watermelon electrolyte drink is agua fresca with a job to do: ripe watermelon blended with cold water, fresh lime, and two scoops of Watermelon Saltivate, for a pitcher that replaces the sodium you lose in sweat with 800mg sodium, 240mg potassium, and 60mg magnesium per glass. Watermelon is a natural fit, light enough to drink fast and sweet enough to carry a salty edge, so doubling the melon with Watermelon Saltivate just makes the glass taste more like itself.

Ingredients

Makes 2 glasses, about 16 oz each.

  • 2 scoops Watermelon Saltivate (1 full serving of electrolytes per glass)
  • 4 cups cubed seedless watermelon (about 1 1/2 lbs)
  • 1 cup (240 ml) cold water
  • 2 tbsp fresh lime juice (about 1 large lime)
  • 2 cups ice, for serving
  • Lime wheels, for garnish (optional)

Instructions

  1. Add the watermelon, cold water, and lime juice to a blender.
  2. Blend on high for 30 to 45 seconds, until completely smooth.
  3. If you want a clearer drink, strain through a fine-mesh sieve into a pitcher. For a thicker, juicier texture, skip the strainer.
  4. Add 2 scoops of Watermelon Saltivate and blend for 5 more seconds, or whisk in the pitcher until fully dissolved.
  5. Fill two glasses with ice, pour, and garnish with lime wheels.

Serving suggestions and variations

  • Taste your melon first. A very ripe watermelon may not need all the lime; a paler one benefits from an extra squeeze.
  • Store leftovers in the fridge for up to 2 days. It separates as it sits, so give it a good stir or shake before pouring.
  • Prefer the melon flavor on its own? Swap in Raw Unflavored Saltivate; it is plain, dissolves clear, and adds a clean salty edge that makes the melon taste brighter.

Per serving: about 140 kcal (estimate).
