The ingredients we use is 1 ounce of Bombay Sapphire (blue) dry gin (London or equivalent) 47% al/vol, 1/2 ounce of Blue Curacao liqueur (Vok or equivalent) 23% al/vol, 1/4 fresh squeezed lemon and one maraschino cherry.

Place cracked ice in shaker, add dry gin, curacao and lemon and shake, pour into a martini glass and decorate with 1 marachino cherry.

Enjoy, and take care as the resultant drink is over 30% proof.
