In an Old Fashioned (rocks) glass, add ¼ oz ZingBing simple syrup, 2 dashes Angostura bitters, and 1 dash Fee Brothers Black Walnut bitters.
Add ice sphere to glass and pour 2 oz bourbon over sphere.
With your bar spoon, stir contents of glass to chill the cocktail.
With a vegetable peeler (or knife), remove an inch-wide section of an orange peel. Be sure not to cut past the pith (white part) so that the flesh of the orange isn't exposed.
Strike a match and gently heat the orange part of the rind with the flame for 5-10 seconds.
While holding match between the glass and the peel, give the rind a gentle squeeze to express the oil; the citrus oil will flame and settle onto the drink.
Take the orange side of the peel and rub along the rim of the glass—this will ensure the remaining oil will flavor and scent the entire rim; place orange peel in glass.
Skewer a Filthy® cherry with a garnish pick and toss in glass alongside the peel.
