Ingredient Notes and Substitutions
Use ripe, sweet watermelon for the best flavor. Choose a watermelon that feels heavy for its size, has a creamy yellow field spot, and makes a deep hollow sound when tapped. A naturally sweet watermelon means you may need less sugar. For more helpful tips, see this guide to choosing a ripe watermelon.
Sabja seeds are also called basil seeds. Soak them before using so they soften, expand, and develop their signature gel-like coating. Soaking them separately before adding them to the drink helps them hydrate evenly and keeps the watermelon lemonade smooth. See Serious Eats’ guide to basil seeds in drinks for more helpful tips.
You can use lime juice or lemon juice in this recipe. Lime gives a slightly more tropical and fresh flavor, while lemon gives a classic lemonade taste. For a simple classic lemon drink without watermelon, try this Best Homemade Lemonade Ever. It is bright, sweet-tart, and easy to make in a pitcher for summer gatherings.
Black salt adds a light tangy, savory note that works very well with watermelon. If you do not have it, use a tiny pinch of regular salt.
Fresh mint adds a cooling finish. Do not skip it if you want the drink to taste extra fresh. For another cool drink with mint and citrus, try this Fresh Cucumber Lemonade with Mint. Its crisp cucumber flavor makes it a refreshing choice for hot days.
How to Make Watermelon Lemonade
- Add the sabja seeds to 1/2 cup water and let them soak for 10 to 15 minutes, until they swell.
- Add the watermelon cubes, mint leaves, lime or lemon juice, sugar, black salt, and 1 cup cold water to a blender.
- Blend until smooth.
- Strain the mixture through a fine mesh strainer into a jug to remove excess pulp.
- Add a few small watermelon chunks and some soaked sabja seeds to each serving glass.
- Fill the glasses with ice cubes.
- Pour the strained watermelon lemonade into the glasses.
- Garnish with extra mint and serve immediately.
Expert Tips for the Best Watermelon Lemonade
- Use chilled watermelon so the drink stays cold and refreshing.
- Taste the watermelon first and adjust the sugar based on sweetness.
- Strain the juice if you want a smoother and lighter drink.
- Do not add too much black salt. A small pinch is enough.
- Soak the sabja seeds fully before serving for the right texture.
- Add the watermelon chunks just before serving so they stay fresh.
- Use fresh lime or lemon juice, not bottled juice, for the brightest flavor. For juicier citrus, roll the whole lime or lemon firmly on the counter before cutting. If it feels especially firm, microwave the whole uncut fruit for 15 to 20 seconds, then let it cool slightly before juicing. See Simply Recipes’ trick for getting more juice from lemons and limes.
- Serve immediately over ice for the freshest taste.
Storage and Freezing
Store the strained watermelon lemonade in a covered jug in the refrigerator for up to 1 day.
Keep the soaked sabja seeds separate and add them just before serving for the best texture.
This drink is best served fresh and is not ideal for long storage because the watermelon flavor is brightest on the first day.
You can freeze watermelon cubes and blend them later for a colder, slushier version.
Can I Make Watermelon Lemonade Ahead?
Yes. You can blend and strain the watermelon lemonade a few hours ahead, then keep it covered in the refrigerator. For the freshest texture, add the soaked basil seeds, watermelon chunks, mint, and ice just before serving.
