1. Step
Pour 50 ml of ginger-lemon syrup into a large glass or pitcher. Add 350 ml of cold water or sparkling water. Thanks to the 1:7 ratio, the drink will have a pleasantly intense flavor, but if you prefer a milder taste, you can add more water.
Fill the glass or pitcher with ice cubes to make the drink even more refreshing.
2. Step
Add a few lemon or lime slices and berries to the glass or pitcher. Add a few sprigs of fresh mint or rosemary.
Stir the drink with a spoon so the flavors blend well. Garnish the glass with a lemon slice on the rim, and top it with a little mint or rosemary.
3. Step
If you want an even more intense flavor, you can add a little freshly grated ginger.
