Why it works: Cinnamon and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓

Ingredients
Directions
Prepare

Place the rhubarb in a preserve kettle.
Cook

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Provides the main body and tart flavour of the preserve.
- Sugar
- Sweetens the preserve and helps it thicken as it cooks down.
- Vinegar
- Adds acidity that balances the sweetness and brightens the flavour.
The step that matters
Simmer until marmalade consistency. Rhubarb releases water and pectin slowly, so the mixture thickens only as moisture evaporates. Stopping too early leaves it runny, while cooking too long can scorch the sugar and make it stiff.
Swap the rhubarb
How well each one fits the dish's main ingredients (vinegar, sugar, cinnamon, clove):
- Allspicefits better
- Nutmegfits better
- Cardamomfits better
- Rhubarbthe original
Fit is the average pairing score against vinegar, sugar, cinnamon, clove. Candidates are from the same food group and used in at least 100 recipes.
