Lu Brow, the former cocktail director at New Orleans’ (now-closed) DTB, incorporated the nutty, toasty flavor of brown butter into this classic cocktail. This Brown Butter Old Fashioned features a base of brown butter-infused bourbon.

Brown sugar lends an earthy sweetness to the classic Bourbon Old Fashioned, while the classic Angostura bitters lend spice and a muddled maraschino cherry imparts a rich fruitiness. This takes a little extra time to construct. But this drink is ultimately easy to make at home.

To incorporate the brown butter, heat unsalted butter in a saucepan until it has a nutty aroma. Then add the browned butter to a bottle of bourbon, freeze it, and skim off the solids. What remains is a rich, buttery whiskey.

Brown Butter Washed Bourbon Recipe

Ingredients
1/2 cup unsalted butter
750 mL bourbon

Directions
Slowly brown 1/2 cup unsalted butter in a saucepan until it is well-toasted and has a nutty aroma. Remove the pan from the heat and allow to cool.

Pour the bottle of bourbon into a freezer-proof container, and gently stir in the brown butter.

Leave the mixture uncovered until it is completely cool and the butter has become firm and rises to the top of the container. Then, freeze the bourbon mixture. When the butter is solid, skim it off and strain the bourbon through a cheesecloth to remove any remaining solids.

Cover, label, and date. The bourbon will keep for a few weeks.
