Why it works: Plum and cinnamon match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 513 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓
Spiced Plums
Ingredients
Directions
Make the syrup
In a large pot, boil the vinegar, sugar, and cinnamon together.
Pour the hot mixture over the plums.
Steep over five days
The next morning, draw off the liquid and boil it again.
Pour the boiled liquid back over the plums.
Repeat the boiling process for five mornings.
Finish
On the last day, boil the plums for about 20 minutes.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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
- Blue plums
- Provide the fruit body that softens and absorbs the spiced syrup as it steeps.
- Sugar
- Adds sweetness and body to the syrup and helps preserve the fruit.
- Vinegar
- Adds sharp acidity that balances the sweetness and helps preserve the fruit.
- Cinnamon
- Adds warm spiced aroma that infuses the syrup and the plums.
The step that matters
Draw off and reboil the syrup each morning. Reboiling the drained syrup before pouring it back keeps it hot and concentrated, so it penetrates the fruit and helps preserve it. Skipping a boil lets the syrup cool and weaken.
Swap the plum
How well each one fits the dish's main ingredients (sugar, vinegar, cinnamon):
- Vanillafits better
- Raisinfits about as well
- Figfits about as well
- Plumthe original
Fit is the average pairing score against sugar, vinegar, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
