Why make this drink?

- No Artificial Flavors or Colors: By using fresh fruit and natural sweeteners, this recipe avoids artificial additives.

Ingredients and substitutes
- Watermelon – The best watermelons are the ones that are bright red and juicy. A good practice is to let the grocer cut and check before you buy, so you know that you’re getting a good one. I like to strain the pureed watermelon through a fine mesh strainer because it looks nicer and it’s smoother to drink. Having said that, pulp is a good fiber and is good for you.
- Lemon juice – There is nothing more refreshing than fresh lemon juice. You can also use lime juice. I like to use Meyer lemons.
- Sugar – I use white sugar, but simple syrup or honey also works. Adjust the sweetness depending on how sweet the watermelon is.
- Liquid – I like to use sweet sparkling water so that I can omit the sugar, but you can also use classic sparkling water or plain water.
- Garnish – I usually use fresh lemon wedges, watermelon wedges, or fresh basil or mint leaves. You can also use the curled lemon rind.

Step-by-step: Watermelon lemonade
- In a small saucepan, combine the sugar and 1/2 cup of water, and heat over medium heat, stirring, until the sugar dissolves. Let the syrup cool.
- In a blender, puree the watermelon until smooth. Strain the puree through a fine-mesh sieve into a large pitcher, pressing on solids to extract as much juice as possible.
- Add the lemon juice, sugar syrup, and cold still or sparkling water to the pitcher with the watermelon juice. Stir to combine.
- Taste and adjust the sweetness if necessary by adding more sugar.
- Serve over ice cubes, garnished with lemon slices and mint leaves if desired.


Frequently asked questions
Watermelon lemonade will last for about 2-3 days in the refrigerator. After that, the flavor may start to degrade.
Yes, you can use honey, agave syrup, or simple syrup as a substitute for sugar. Adjust the amount based on your preferred level of sweetness.
While a blender makes it easier to puree the watermelon, you can still make watermelon lemonade without one. Simply mash the watermelon with a fork or potato masher and strain the juice through a sieve.
Yes, you can use lime juice instead of lemon juice for a slightly different flavor. Lime juice tends to be a bit more tart than lemon juice, so you may need to adjust the sweetness accordingly.
Yes, you can add vodka, rum, or tequila to watermelon lemonade to make a refreshing summer cocktail. Adjust the amount of alcohol based on your preference.

Notes

-
- Use Fresh Lemons: Freshly squeezed lemon juice will give your lemonade a bright, vibrant flavor. Avoid using bottled lemon juice if possible.
-
- Adjust Sweetness: Taste the lemonade before serving and adjust the amount of sugar or sweetener as needed. Some watermelons are sweeter than others, so that you may need more or less sugar.
-
- Strain the Watermelon: Strain the watermelon puree through a fine-mesh sieve to remove any pulp or seeds. This will give your lemonade a smooth consistency.
-
- Chill Before Serving: For the most refreshing experience, chill the lemonade in the refrigerator for at least an hour before serving. You can also serve it over ice cubes.
-
- Garnish for Presentation: Add a slice of lemon and a sprig of mint to each glass for a beautiful presentation. This is especially nice if you serve lemonade at a party or gathering.
