WHAT YOU NEED
Ingredients
- White Grape Lemon Juice Blend
- Watermelon Juice Blend
- Sweetener
METHOD
How to make it
- Prep Your Ingredients: Begin by preparing your watermelon, cutting it into chunks, and ensuring no seeds are present. Squeeze fresh lemons to get the required juice.
- Blend the Watermelon: In a blender, add the watermelon chunks. Blend on high until you have a smooth juice consistency. You might want to strain the juice using a fine mesh to get rid of any pulp, but that's optional based on preference.
- Mix Your Juices: Add the watermelon juice to the blender with the white grape juice and lemon juice. Blend these together briefly to ensure they’re well combined.
- Add the Sweetener: Now, introduce the Turbinado sugar to the blender. Blend again until the sugar is completely dissolved. Taste and adjust the lemon juice or sugar according to your liking.
- Chill: For the best flavor, chill the mixture in the refrigerator for about an hour or serve over ice immediately for a refreshing drink.
- Serve: Pour into your favorite glass, garnish with a slice of lemon or watermelon if desired, and enjoy!

Smoothie King Watermelon Lemonade Homemade Recipe
Smoothie King Watermelon Lemonade is a refreshing smoothie option that combines the flavors of watermelon and lemonade. It’s designed to be a light, hydrating drink with a balanced sweetness from the watermelon and tanginess from the lemonade.
Tips for Perfecting Your Smoothie King Watermelon Lemonade:
- Select Ripe Watermelon: For a sweeter, more flavorful smoothie, ensure your watermelon is ripe. A good indicator is a watermelon that feels heavy for its size and has a creamy yellow spot where it rests on the ground.
- Adjust Sweetness and Tartness: The beauty of making this drink at home is the ability to customize it. Start with less lemon juice and sweetener, then adjust to taste. Remember, you can always add more but can't take it away.
- Chill Your Ingredients: For an extra refreshing smoothie, chill your watermelon and white grape juice before blending.
- Make It a Smoothie: If you prefer a more traditional smoothie consistency, add a cup of ice before blending.
- Sweetener Substitutions: If Turbinado sugar isn't available, feel free to use other sweeteners. Liquid sweeteners like honey or agave nectar mix particularly well.
What to serve with
This light, fruity drink suits summer food: fruit or caprese skewers, grilled chicken or fish, and a quinoa or couscous salad. For dessert, try sorbet or angel food cake.
Ingredients Substitutes

Creating a homemade version of Smoothie King’s Watermelon Lemonade can be both fun and satisfying. However, if you don’t have all the exact ingredients on hand or wish to make some adjustments to suit dietary preferences or enhance nutritional content, consider using substitutes.
Watermelon
Primary Ingredient: Watermelon is crucial for its juicy, sweet flavor.
Substitutes: If watermelon isn’t available or if you’re looking for a different taste profile, you can try other melons like cantaloupe or honeydew. These will alter the flavor but still provide a similar sweetness and hydrating effect.
Lemon Juice
Primary Ingredient: Fresh lemon juice provides tartness and brightness, balancing the sweetness of the watermelon.
Substitutes: Lime juice can be a direct substitute, offering a slightly different citrus note. Apple cider vinegar is another alternative, although more potent, so use it sparingly to avoid overpowering the drink.
Sweetener (e.g., Honey, Sugar)
Primary Ingredient: Typically, some form of sweetener is added to enhance the watermelon's natural sweetness.
Substitutes:
- Agave syrup: A natural sweetener that is sweeter than sugar, use less quantity.
- Stevia or monk fruit sweetener: For a sugar-free version, these are great options. They are much sweeter than sugar, so adjust according to taste.
- Maple syrup: This can provide a unique flavor twist besides sweetening the drink.
Final Thoughts
The light, refreshing Smoothie King Watermelon Lemonade pairs best with foods that are not too heavy or overpowering, allowing both your meal and the drink to shine. Enjoy experimenting with these suggestions to find your perfect summer pairing!
