Why it works: Rhubarb and orange work together. They rank in the top 5% of all ingredient pairs, and cooks put them together in 299 recipes. Both carry 2-methoxy-4-vinylphenol, which smells clove, smoky. The science ↓
Pine-apple and Rhubarb Marmalade
Ingredients
Directions
Prepare the fruit
Remove the pineapple from the tin and chop it into small pieces.
Cook the pineapple in its own juice until tender.
In a separate pot, stew the rhubarb until soft.
Make the marmalade
Mix the cooked rhubarb with the pineapple and cook together for a few minutes.
For every pint of the mixture, add 10 oz of sugar and boil for 20 minutes.
Store the marmalade in small glass jars.

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):
- Vanillafits better
- Lemonfits better
- Figfits better
- 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.
