2 oz. Bombay Sapphire Gin
1-2 oz. Fresh Lemon juice
1 oz. Mint simple syrup
Fresh mint leaves
Fill a shaker half full with ice. Add Gin, mint syrup and lemon juice. Next add 5-6 fresh mint leaves. Shake vigorously for 20 seconds, double strain into an ice filled Collins glass and top off with tonic or seltzer water. Last take one mint leaf and give it a good smack to release the oils and scent, then add it to the drink.
Note; Mint simple syrup is made by combining 1 part sugar and 1 part water along with a generous handful of mint leaves and boiling them for about ten minutes in a sauce pan. Let cool then strain into a container and refrigerate. This is a vital element to the cocktail and one that cannot be skimped on.
