Cucumber Lemonade Chiller

1- Remove the skin of the cucumber and add it to a blender along with the rosemary and a dash of sugar syrup
2- Blend
3- Add the blended mixture to your shaker with the gin and the lemon juice
4- Shake with ice
5- Serve double-strained zon ice cubes
6- (optional) Top up with soda water
7- Decorate the glass with rosemary

Additional notes: The proportion of cucumber and rosemary can be scaled up a lot if you like it more "intense". I personally like to double those proportions to have a more intensive taste, but the cocktail will be as well balanced after.
