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

What each ingredient does

Carrots
Provide the bulk and body of the marmalade as they soften and thicken.
Apples
Add pectin and body, helping the marmalade thicken as it cooks.
Sugar
Sweetens the marmalade and helps it set into a thick, spreadable texture.
Lemon juice
Adds acidity that balances sweetness and brightens the flavour.

The step that matters

Simmering until thick. Cooking gently over low heat lets the mixture thicken slowly without scorching on the bottom of the pot. Sugar and fruit set as water evaporates, so stopping too early leaves it runny.

Swap the carrot

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

  1. Arrowrootfits better
  2. Sweet potatofits better
  3. Parsnipfits better
  4. Carrotthe original

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