The Brain Duster is a classic cocktail that was created by George J. Kappeler in 1895 at the bar of New York City’s Waldorf Astoria Hotel. It’s traditionally made with an equal-parts combination of rye whiskey, absinthe, and sweet vermouth, a dash of bitters, and citrus. It’s also said to have been named for its potency.
Add rye, absinthe, vermouth, 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.
Using a julep strainer, strain into a martini or Nick & Nora glass.
Garnish with lemon twist.
