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

What each ingredient does

Yellow tomatoes
Provide the main body and bulk of the marmalade.
Grated pineapple
Adds tangy flavor and acidity that brightens the sweet tomato base.
Granulated sugar
Sweetens the marmalade and, as it cooks down, helps it thicken and keep.

The step that matters

Cook slowly for 1 hour after adding the sugar. Sugar dissolves and the mixture must be cooked long enough for water to evaporate, so the fruit thickens into a spreadable set. Cooking too fast can scorch the sugar and fruit on the bottom of the kettle before the texture develops.

Swap the tomato

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

  1. Capsicumfits better
  2. Sweet potatofits better
  3. Arrowrootfits better
  4. Tomatothe original

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