Ingredients
  

  • 1 cup granulated sugar
  • 5-6 cups cold water
  • 8 cups cubed watermelon
  • 1 cup freshly squeezed lemon juice
  • 4 cups ice
  • 1 1/2 cups lemonade
  • 1 tablespoon fresh mint or basil (optional)

Method
 

  1. Make the simple syrup: Combine granulated sugar with 1 cup of water in a small saucepan. Heat gently until the sugar dissolves completely (about 2 minutes). Let it cool.
  2. Prepare the watermelon base: Puree half the cubed watermelon with 1 cup of cold water in a blender until smooth. Strain through a fine-mesh sieve into a large bowl, discarding solids. Repeat with the remaining watermelon and another cup of water.
  3. Combine the lemonade base: To the bowl with the strained watermelon juice, add the remaining 2 cups of water, the freshly squeezed lemon juice, and the cooled sugar syrup. Whisk everything together. Taste and adjust sweetness by adding more water if needed. Store in a pitcher in the refrigerator.
  4. Create the slushy: In a blender, combine the ice and the lemonade. Blend until you achieve a smooth, slushy consistency. Add fresh mint or basil now if you like, and blend briefly.
  5. Serve immediately: Pour the slushy mixture into glasses. If desired, top with a sprig of mint/basil. Enjoy your incredibly refreshing drink!

Notes

The technique that makes it

The key to a perfectly smooth and refreshing watermelon lemonade slushie lies in the preparation of the watermelon and the balance of sweetness and tartness. First, ensuring your watermelon is well-chilled before blending is crucial. This helps achieve the desired slushy consistency without diluting the flavor too much with excessive ice. Cubing the watermelon and freezing some of it beforehand can further enhance the icy texture. The recipe calls for making a simple syrup with granulated sugar and cold water. This step is vital because dissolving sugar directly into a cold liquid like lemon juice or watermelon can be difficult, leading to a gritty texture. Boiling the sugar and water together until the sugar is completely dissolved creates a smooth, homogenous syrup that integrates seamlessly into the slushie base. This also allows for precise control over the sweetness. The ratio of watermelon to lemon juice and lemonade is also important. The watermelon provides the primary fruity sweetness and liquid base, while the lemon juice adds essential tartness to cut through the sweetness and prevent the slushie from tasting cloying. The addition of pre-made lemonade further boosts the citrus flavor and adds another layer of complexity. Blending all the ingredients, including the ice, until smooth but not overly watery is the final technique. Over-blending can melt the ice too quickly, resulting in a drinkable juice rather than a slushie.

Troubleshooting

  • Problem: Slushie is too icy and hard to blend.
    Fix: Add a little more liquid, such as cold water, lemonade, or even a splash of the unfrozen watermelon juice, and blend again. You can also let it sit at room temperature for a few minutes to soften slightly.
  • Problem: Slushie is too watery and not thick enough.
    Fix: Add more frozen watermelon cubes or ice, and blend again until the desired consistency is reached. Ensure your watermelon was well-chilled or partially frozen before blending.
  • Problem: Slushie is too sweet.
    Fix: Increase the amount of fresh lemon juice or add a bit more cold water. You can also add a small amount of unsweetened cranberry juice for a tart counterpoint.
  • Problem: Slushie is not sweet enough.
    Fix: Gradually add more of the prepared simple syrup, or a touch more lemonade, blending after each addition until the sweetness is balanced to your preference.

Substitutions

  • Sweetener: Instead of granulated sugar for the simple syrup, you can use honey or agave nectar. Use approximately 3/4 cup of honey or agave for the same sweetness level, but be aware it may slightly alter the flavor profile.
  • Lemon Juice: If fresh lemons are unavailable, bottled lemon juice can be used, though the flavor will be less bright. Use about 1 cup of bottled juice. Lime juice can also be substituted for a different citrus note, using about 3/4 cup of fresh lime juice.
  • Lemonade: For a less sweet or more tart slushie, you can substitute the lemonade with an equal amount of sparkling water infused with lemon or lime zest. This will reduce sweetness and add effervescence.
  • Herbs: If mint or basil are not preferred or available, consider adding a small amount of fresh ginger (about 1/2 inch, peeled and roughly chopped) to the blender for a spicy kick, or omit the herbs entirely for a cleaner watermelon-lemon flavor.

Pro tips

  • For an extra fruity kick, use a blend of watermelon varieties.
  • Adjust the sugar syrup to your personal preference; less sugar makes for a tarter drink.
  • Garnish with a slice of lemon, a small watermelon wedge, or a sprig of mint for a beautiful presentation.

Frequently asked questions

Can I make watermelon lemonade slushie ahead of time?

You can prepare the watermelon puree and lemon juice mixture a day in advance and store it in the refrigerator. However, it’s best to blend it with ice just before serving for the optimal slushy consistency. Freezing the mixture solid will make it difficult to re-blend into a slush.

What can I use instead of watermelon for slushies?

Cantaloupe or honeydew melon are excellent substitutes for watermelon in this recipe. They offer a similar sweet, watery base. You could also try using a mix of berries like strawberries and raspberries, though this will alter the flavor profile and color significantly.

How to store leftover watermelon lemonade slushie?

Leftover slushie can be stored in the freezer in an airtight container. It will likely freeze solid. To serve, let it sit at room temperature for about 15-20 minutes to soften slightly, then re-blend in a powerful blender or stir vigorously to break up ice crystals.

How to make watermelon lemonade slushie sweeter or tarter?

For a sweeter slushie, add more sweetener like agave nectar or maple syrup, starting with a tablespoon at a time and tasting. To make it tarter, increase the amount of fresh lemon juice. Adjusting these components allows you to perfectly balance the sweet and tart flavors to your preference.
