The Elderflower Old Fashioned is a spring cocktail of unknown origin that was first published in a 2014 issue of Saveur. The recipe is a simple variation of the classic Old Fashioned that also uses whiskey as the base spirit and aromatic bitters, but it omits the orange and calls for elderflower liqueur as a sweetener in addition to simple syrup.
Add bourbon, elderflower liqueur, simple syrup, and bitters to a mixing glass.
Fill mixing glass with cubed ice.
Using a bar spoon, stir for 30-45 seconds until well-chilled and slightly diluted.
Add a clear ice cube to a lowball glass.
Using a julep strainer, strain into lowball glass.
Garnish with lemon twist.
