In a mixing glass with ice, combine 2 ounces gin, 1/2 ounce Zirbenz, and 1/2 ounce dry vermouth, plus a 1/4 ounce simple syrup and 1 dash orange bitters. Stir until very well-chilled, then strain into a chilled coupe or martini glass. Garnish with a lemon peel, twisting over the surface of the drink to spray its citrus oils into the glass.
