Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Plum Preserves
Ingredients
Directions
Prepare
Wash and pick the plums, then place them in a stone jar.
Combine equal weights of sugar and water in a pot to make a thick syrup.
Boil the syrup and skim off any foam.
Pour the hot syrup over the plums and cover with a plate.
Soak and reboil
Drain off the syrup from the plums.
Boil the drained syrup again.
Skim the boiled syrup.
Pour the boiled syrup back over the plums.
Repeat steps 5-8 for three to four days.
Cook the preserves
Place the plums and syrup in a kettle.
Boil very slowly for half an hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Plums
- The main fruit; it supplies the flavor and the body of the finished preserve.
- Sugar
- Preserves the fruit and thickens the syrup, adding sweetness and body.
The step that matters
Repeated draining and reboiling of the syrup. Each boil concentrates the sugar syrup and draws water out of the fruit, which helps preserve it. Skipping repeats or boiling too hard can leave the plums tough or the syrup thin.
Swap the plum
How well each one fits the dish's main ingredients (sugar, syrup):
- Vanillafits better
- Raisinfits better
- Pearfits better
- Plumthe original
Fit is the average pairing score against sugar, syrup. Candidates are from the same food group and used in at least 100 recipes.
