Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Blackberry juice: Provides the main fruit flavor, color, and liquid base of the cordial.
Granulated sugar: Sweetens the cordial and helps preserve it by binding water.
Rye whiskey: Adds alcohol that helps preserve the cordial and contributes its own flavor.
Allspice: Adds warm, aromatic spice notes to the cordial.
Cloves: Adds strong, warm aroma and spice flavor.

The step that matters

Stir in the rye whiskey only after cooling. Alcohol evaporates readily when hot, so adding the whiskey after the mixture has cooled keeps more of its alcohol and flavor in the cordial, which also helps preservation.
