Step 1 Add the gin, Carpano Antica, maraschino liqueur and orange bitters to a mixing glass filled with ice. Stir and strain into a chilled coupe.
Step 2 To make an orange twist, use a channel or paring knife to cut a thin strip of orange peel 2 to 3 inches long. Twist the peel into a "spring" shape over the finished drink to release the oils and drop the twist into the drink.
