Finally! The making of the martini. You should experiment with a few different gin’s and vermouth to find what you like and also experiment with the ratio of gin to vermouth. Remember to NEVER shake your martini.   Take a cold mixing glass. Fill it with ice. Add 5-10 ml of vermouth to the glass. Add 3 oz. bombay sapphire gin. Stir well. Strain the cocktail in a chilled martini glass. Garnish with a lemon twist. It's known as Bombay Sapphire Dry Martini with a Twist.
