1 dash Orange bitters
10ml Noilly Prat Original Dry vermouth
60ml Bombay Sapphire London dry gin
1. Stir with solid ice cubes until very cold and diluted to perfection
2. Garnish with an olive, lemon twist or pickled onions
However, Ladislav himself actually prefers a 3:1 ratio of gin to vermouth, so maybe you can try both to see which you prefer!
