Shake, strain, up, cocktail glass, sugared rim. A puddle of ginger will settle to the bottom of the glass.
Spicy hot undertones. Much of the ginger is left in the shaker. Either use plenty or add some directly to glass.
Originally called a Ginger Martini from Lucy Too, a bar in Akumal, Mexico. Originally called for a float of Grand Marnier, but the dense liqueur sinks to the bottom of the glass, making the last sips too sweet.
