Rub a freshly cut lemon on the side of your serving glass where you want the sugar to go.
Dip the wet part of the glass into the sugar so it sticks.
If you would like to chill the glass, add some ice and water to the glass at this point. Just be careful in dumping the water out before you pour in the cocktail, so you don't disturb the sugared rim. You could also just stick the glass in the fridge or freezer for a few minutes.
Make the drink
Measure and add the gin, Creme de Violette, lemon juice, simple syrup, ginger juice and bitters to a cocktail shaker.
Shake all ingredients with ice, about 15-20 times or until well chilled.
Strain the drink into your prepared cocktail glass and serve immediately.
