Try this modern San Francisco classic.
Stir together the cinnamon and sugar in a wide-mouthed bowl or on a saucer.
Rub the rim of a chilled cocktail glass with the lemon wedge and dip in the cinnamon-sugar mixture to coat.
Add the remaining ingredients to a shaker and fill with ice.
Shake, and strain into the prepared glass and garnish with an orange spiral.
