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

What each ingredient does

Pineapple
Provides the fruit base and its natural pectin and acidity help the marmalade thicken and set.
Sugar
Sweetens the fruit and, as it cooks down, thickens the mixture into a preserve that keeps well.

The step that matters

Cooking until thick. Cooking must continue until the mixture reaches a thick, spreadable consistency. Sugar and fruit set as water evaporates and the concentration rises, so stopping early leaves a runny preserve that may spoil sooner. Larger batches take longer to reduce.

Swap the pineapple

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

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

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