What to you get when you combine a smoky whisky, a French herbal liqueur dating back to 1737 (the Carthusian Monks were fans) and vibrant citrus flavours? You’re about to find out. 

Ingredients
45ml (1.5 oz) Peated Finish
10ml (0.4 oz) Yellow Chartreuse
10ml (0.4 oz) Fino sherry
10ml (0.4 oz) Lemon juice
10ml (0.4 oz) Simple syrup
60ml (2 oz) Tonic water

Pull it together
Grab some crushed ice, pop it in a small glass tumbler and pour in the ingredients one by one. Give it a good swivel and top if off with a slice of cucumber to garnish like a pro.
