- 0.3 ml lemon juice
- 1 × soda water
- 500 g watermelon
- 20 g cane sugar
Fill the iSi Sodamaker Classic or the iSi Soda Siphon with cold water. Screw on 1 iSi soda charger and shake vigorously. To ensure the water is really fizzy refrigerate for 1-2 hours.
Remove the peel from a water melon, puree it finely with the sugar, and put it into a saucepan or metal bowl.
Place the bowl in a container full of ice cubes to cool it down. It will cool faster if you stir it now and then!
Add some lemon to taste, and fill a bar tumbler three quarters full with the melon mousse until it is three quarters full. Finally top it up with fresh soda from the iSi Sodamaker Classic.
