Perhaps the first cocktail ever mixed, the Old Fashioned has seen many incarnations, including the current (and loathsome) trend of muddling cherry and orange into it. Rye was the first whiskey used with this drink, and Angostura bitters are most commonly mixed in. I’ve switched rye for Bourbon, and Peychaud’s bitters for a slightly sweet and more floral cocktail. Learning to adjust to your taste preferences is all part of becoming a great home bartender.
In a mixing glass, combine all ingredients, and stir over ice until cold. Strain over ice into a highball glass, and garnish with the lemon twist.
