Blast the lemongrass with the back of a knife and cut into pieces. Bring to a boil with half a liter of water and the sugar and continue to simmer over low heat for about 5 minutes. Allow to cool. Pat the washed cucumbers dry and roughly dice them. Finely chop the cucumber cubes in a blender and pass through a fine sieve. Halve 4 lemons and squeeze the juices. Mix about 200 ml of lemon juice with the cucumber water. Strain the lemongrass syrup. Add the cucumber water and chill for one hour.
