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

What each ingredient does

Pears
Provide the bulk of the fruit, giving the marmalade its body and pieces of texture.
Sugar
Sweetens the marmalade and, as it thickens with cooking, helps it set to a spreadable consistency.
Lemon juice
Adds acidity that brightens the flavor and supports gelling and color.
Pineapple
Adds its own fruit flavor and softens into the mixture during boiling.

The step that matters

Boil until the mixture reaches a nice consistency and color. Sugar and fruit pectin set only after enough water evaporates and the mixture reaches the right concentration. Stopping too early leaves it runny, while overcooking can darken it and make it stiff.

Swap the lemon

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

  1. Vanillafits better
  2. Plumfits better
  3. Applefits better
  4. Lemonthe original

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