You will need:
- A lime
- Angostura bitters
- Egg whites
Mix together 50ml gin, 20ml lime juice, 10ml soda, egg whites from one egg and a dash of angostura bitters in a cocktail shaker. Shake hard, then pour into a martini glass. The egg whites should form a froth on top, and you can add a twist of lime for a professional touch.
Unfortunately the 'turbo' effects only last for the evening.
