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

What each ingredient does

Oranges
Peel and pulp supply bitterness and pectin that help the marmalade set.
Lemons
Add acidity and extra pectin that help the marmalade set and brighten flavour.
Brown sugar
Sweetens the marmalade and thickens it as the syrup cooks down.
Vinegar
Adds acidity that brightens flavour and supports a good set.
Whole cloves
Add warm, aromatic spice flavour.

The step that matters

Final boiling until it jells. Setting depends on enough sugar, acid and pectin being concentrated by boiling. Stopping too early leaves the marmalade runny, while boiling too long can scorch the sugar and make it hard.

Swap the clove

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

  1. Cinnamonfits better
  2. Peppermintfits better
  3. Tarragonfits better
  4. Clovethe original

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