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

What each ingredient does

Pineapple chunks
Provides the main fruit body and sweet tropical flavour to the marmalade.
Rhubarb
Adds tartness and bulk, balancing the sweetness of the pineapple and sugar.
Sugar
Sweetens the mixture and, as it boils, helps thicken it into a spreadable set.
Oranges
Contribute acidity and citrus aroma, and their juice helps the marmalade set.

The step that matters

Boiling with the sugar for 20 minutes. Sugar must dissolve fully and the mixture must reach a rolling boil for long enough that the sugar and fruit pectin set properly. Too short a boil leaves the marmalade runny, while over-boiling can darken and scorch it.

Swap the pineapple

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

  1. Vanillafits better
  2. Lemonfits better
  3. Figfits better
  4. Pineapplethe original

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