This lemonade is a summer classic, characterized by the combination of sweet watermelon and fresh mint. The sugar dissolves better if it is mixed with the lime juice before the mint is added – this way, it releases its aroma without any bitter substances. A drink that not only tastes great but also looks impressive: the bright red color of the melon and the rich green of the mint make it a real eye-catcher.
And here’s what you need for the Watermelon Mint Lemonade
1 kg ripe watermelon (yields approx. 500 ml juice)
Juice of 2 limes (approx. 4 cl)
1 handful fresh mint leaves (approx. 10 g)
4 tbsp sugar (approx. 50 g)
1 litre sparkling water
Ice cubes to top up
This is what matters
The trick lies in the timing of the mint: if it comes into contact with the sugar too early, it releases bitter substances. It is better to add it only after the sugar-lime mixture and to press it lightly – this keeps the aroma fresh and not soapy. Those who prefer a stronger taste can rub the mint leaves briefly between their fingers beforehand to release the essential oils. For a clear appearance, strain the melon juice through a coffee filter – this removes even the finest particles.
Variations
- Watermelon Mint Spritz — For an alcoholic version, add 4 cl vodka or white rum per glass and top up with Prosecco instead of sparkling water. The alcohol should only be added after the sugar and mint to prevent the flavors from being overpowered.
- Ginger Watermelon Lemonade — Stir in 2 cl freshly pressed ginger juice or 1 cl ginger syrup – this adds a spicy note that balances the sweetness of the melon. Particularly good with brown sugar instead of white sugar.
- Watermelon Mint Iced Tea — Replace the sparkling water with 1 litre of cold hibiscus or green tea. The tannins in the tea perfectly complement the mint and make the drink less sweet but more complex in flavor.
Frequently Asked Questions
Can I use frozen watermelon?
Yes, but the juice will be more watery. It is better to use fresh melon and freeze the juice in portions – this preserves the aroma. If frozen melon is used, thaw the juice before mixing and strain it to remove any ice residue.
How long does the lemonade keep in the fridge?
Without sparkling water and ice, it keeps for 1–2 days, although the mint quickly loses its freshness. It is better to prepare the melon juice and sugar-lime mixture separately and mix them only shortly before serving. With sparkling water, the lemonade should be drunk immediately as it will otherwise go flat.
Can I use other sweeteners instead of sugar?
Agave syrup or honey work well, but they change the taste. Honey gives a floral note, agave syrup is more neutral. Both should be dissolved in warm water in a 1:1 ratio before being added to the lime juice so that they mix better.
