Fill a mixing glass two-thirds full with ice.

Add the rye whiskey, sweet vermouth, and Angostura bitters.

Stir continuously for approximately 30 seconds (about 30 rotations).

Strain into a chilled coupe or cocktail glass.

Express the orange peel over the glass by squeezing it skin-side down to release the oils.

Drop in a Luxardo cherry and serve immediately.
