Oolong Old Fashioned Recipe

Brown the butter

In a small skillet over medium heat, melt the unsalted butter. Continue cooking, swirling the pan occasionally, until the butter foams and turns a deep golden-brown with a nutty aroma, about 4–6 minutes. Remove from heat immediately to avoid burning.

Combine sugars and water

In a small saucepan, combine the light brown sugar, granulated sugar, and water. Stir to wet the sugars. Bring to a gentle simmer over medium heat, stirring so the sugars dissolve, about 3–4 minutes.

Incorporate brown butter

Slowly whisk the browned butter into the simmering sugar-water mixture until fully combined. Reduce heat to low and simmer gently for 2 minutes to meld flavors.

Infuse with oolong

Remove saucepan from heat and add the oolong tea leaves. Cover and steep for 6–8 minutes for a pronounced tea character. Taste at 6 minutes; steep longer if you prefer stronger tea notes. Strain the syrup through a fine-mesh sieve or cheesecloth into a heatproof jar, pressing gently on the leaves to extract flavor but avoid bitterness.

Finish and cool

Stir in vanilla extract if using. Let the syrup cool to room temperature, then refrigerate. The syrup will thicken slightly as it cools. Yield: about 1 cup; keeps refrigerated for up to 2 weeks.

Chill and prepare glass: choose an Old Fashioned/rocks glass. Place one large ice cube in the glass or prepare an ice chilled mixing glass if you prefer to stir and strain.

Build the drink: In a mixing glass with a few ice cubes, combine 2 oz The Singleton (single malt), 0.5 oz Ron Santiago de Cuba, 0.5 oz brown butter oolong syrup, and 2 dashes of Angostura bitters.

Stir: Stir the mixture briskly for 20–30 seconds (about 15–20 turns) until properly chilled and slightly diluted (target ~20–25% dilution by volume for classic spirit-forward balance).

Strain and serve: Strain the cocktail over the large ice cube in the prepared rocks glass.

Express and garnish: Express an orange twist over the surface to release oils, rub the rim briefly with the peel if desired, then drop the twist into the glass. Add a dehydrated orange wheel on the rim and, optionally, a short smoked cinnamon stick for aromatic effect.

Finish: Optionally, add one gentle spray of smoked wood or briefly pass the drink under a smoke cloche for added depth. Serve immediately.
