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

What each ingredient does

Blackberries
Provide the fruit flavour and colour that the vinegar takes on.
Cider vinegar
Extracts flavour from the berries and gives the drink its tartness.
Sugar
Balances the acidity and adds sweetness to the reduced juice.

The step that matters

Skimming during the 30-minute boil. Skimming removes foam and impurities that rise as the sugared juice boils, leaving a clearer, cleaner-tasting syrup. Skimming late or not at all can leave the vinegar cloudy and less refined.

Swap the nutmeg

How well each one fits the dish's main ingredients (cider, vinegar, sugar):

  1. Cinnamonfits better
  2. Allspicefits better
  3. Peppermintfits better
  4. Nutmegthe original

Fit is the average pairing score against cider, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
