In our 'Tis the Sea-sun card we sent out in July, we included a delicious recipe for watermelon lemonade. Shout out to our Ambassadors Jenni and Lindsay, who tried out our recipe and suggested accommodations so that everyone can enjoy this summer drink!

Ingredients
4 cups of cubed watermelon (seedless or de-seeded)
1 cup of fresh lemon juice (5-6 large lemons)
1 cup of sugar or 1 cup of simple syrup
4 cups of cold water (adjust to taste)
Ice for serving
Optional garnish: watermelon wedges, lemon slices, or fresh mint
Instructions
Blend & strain: Blend watermelon until smooth. Strain through a fine-mesh sieve to remove pulp (optional for a smoother drink).
Juice lemons: Squeeze lemons and strain juice to remove seeds and excess pulp.
Make simple syrup (optional): Combine 1 cup of sugar with 1 cup of water over medium heat. Stir until dissolved. Cool before using.
Mix it all: In a large pitcher, stir together:
- Watermelon juice
- Lemon juice
- Simple syrup or sugar
- 3-4 cups of cold water (start with 3 and taste-test)
Serve: Pour over ice. Garnish with mint, lemon wheels, or a mini watermelon wedge on the glass rim.
Tips & Variations
Sweetness Adjustments:
Less sweet? Start with ½ cup of sugar or syrup and taste before adding more.
Naturally sweet? Use honey or agave (start with ½ cup).
Low sugar? Try Stevia, monk fruit, coconut sugar, or a sugar-free syrup.
Flavor Boosts:
Add lime juice for a citrus twist (replace ¼ cup of lemon juice).
Stir in a few fresh mint leaves or basil while chilling.
For a tropical vibe, add a splash of pineapple juice (¼ to ½ cup).
Serving and Presentation:
Freeze extra watermelon cubes and use as ice cubes (keeps drink cold without watering it down).
Rim glasses with sugar or chile-lime seasoning for a sweet or tangy finish.
Add a splash of sparkling water or lemon-lime soda just before serving for fizz.

ME/CFS Warrior Version by Lindsay
I had to brainstorm a low-energy version of this as I live with moderate Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and cannot make recipes from scratch. In my version, I used approximately:
6 oz of water.
18 oz of Simply watermelon juice.
A sachet of LMNT lemonade electrolytes in a blender bottle shaker.
I shook the ingredients up and then poured a small glass full and used large ice cubes. It was delicious!
