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 ↓
Rhubarb and Orange Jam
Ingredients
Directions
Prepare
Peel the oranges and remove as much of the white pith as possible.
Divide the oranges, take out the pips, and slice the pulp into a preserving pan.
Add the rind of half the oranges cut into thin strips and the loaf sugar broken into small pieces.
Peel the rhubarb, cut it into thin pieces, and add it to the oranges.
Cook and pot
Stir the mixture over a gentle fire until the jam is done, removing any scum that rises.
Pour the preserve into pots and cover once cool.

Orange and sugar barely smell alike, yet cooks put them together in 19,212 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the tart flavour and fibrous body that gives the jam its structure.
- Oranges
- Supply acidity, aroma and pectin-rich pulp that helps the jam set.
- Loaf sugar
- Sweetens the jam and helps it thicken and keep well.
The step that matters
Stirring over a gentle fire. Gentle heat and regular stirring stop the sugar and fruit from scorching on the base of the pan. Skimming the scum keeps the jam clear and clean-tasting.
Swap the orange
How well each one fits the dish's main ingredients (rhubarb, sugar):
- Vanillafits better
- Figfits about as well
- Quincefits about as well
- Orangethe original
Fit is the average pairing score against rhubarb, sugar. Candidates are from the same food group and used in at least 100 recipes.
