Description

Make this frozen watermelon drink with 4 ingredients plus water. It’s icy, cool and refreshing! Watermelon slushie is the ideal beverage for 4th of July and hot-weather days all summer long.


Ingredients

Scale
  • 12 1/2 cups seedless watermelon, cubed and frozen*
  • Juice of 3 limes
  • 4 1/2 tablespoons agave nectar (blue agave syrup)
  • 1/3 cup fresh mint leaves, lightly packed
  • 6 cups purified water, or more if needed 

*NOTE: The amount of watermelon needed is approximately half of a 15-pound watermelon. I suggest cubing up the whole watermelon. Save the rest to make this recipe a second time.


Instructions

RECIPE PREP THE DAY BEFORE: Slice off watermelon rind and the thin layer of white flesh. Discard. Cube the watermelon into very small pieces. Divide them between 3 zip-top freezer bags, arranging cubes in a single layer. Freeze overnight.

HOW TO MAKE WATERMELON SLUSHIE

  1. Separate the frozen watermelon pieces (snap them apart) so there aren’t large chunks sticking together. 
  2. In order to fit the ingredients in an average size blender, we’ll need to prep this recipe in thirds. So for each batch, add 1/3 of each ingredient to the blender jar: frozen watermelon cubes, lime juice, agave nectar, and mint leaves. Pour in enough water so you’re not over-working the machine to blend the ingredients. Attach the lid. Make sure it’s firmly secured. 
  3. Pulse the blender. Use the tamper. When the frozen watermelon cubes begin to break up, blend until the mixture reaches a slushie consistency. If the mixture is too thick add more water. 
  4. Divide watermelon slushie between tall glasses. Garnish each glass with a small slice of watermelon, a slice of lime, and a few sprigs of fresh mint. For a nice serving presentation, transfer remaining drink to a beverage pitcher.

Notes

KITCHEN SMARTS: When measuring cut pieces of fruit, leave your measuring cups in the drawer. Instead, use a large (8-cup) batter bowl that has cup measurements listed along the sides.

EQUIPMENT NEEDED: A high-speed blender with tamper, or a large food processor.

MELTED WATERMELON SLUSHIE: When this beverage melts, it automatically becomes the base for watermelon limeade. Pour the slushie through a fine-mesh sieve. Discard the solids. Squeeze in more lime juice, if desired, and refrigerate. When ready to serve, fill tall glasses 2/3 full with ice. Add sparkling water to the drink mixture. Pour watermelon limeade over ice.

KID-FRIENDLY IDEA FOR MELTED SLUSHIE: Make watermelon ice pops! Pour the mixture into popsicle molds and freeze until solid, about 12 hours.
