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 the plums
Wash and prick the plums.
Place the plums in a stone jar.
Make the syrup and soak the plums
Combine equal weights of sugar and water in a pot to make a thick syrup.
Boil the syrup and skim off the foam.
Pour the hot syrup over the plums.
Cover the plums with a plate.
Drain off the syrup from the plums.
Boil the syrup again and skim it.
Pour the syrup over the plums.
Repeat the previous process for three to four days.
Cook and store
Place the plums and syrup in a preserving kettle.
Boil very slowly for half an hour.
Transfer the preserves to stone jars, cover with paper like jellies, or seal in cans.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Plums
- Provide the fruit, which softens and holds its shape in the thick syrup.
- Sugar
- Sweetens the fruit and, with heat, thickens the syrup and helps preserve the plums.
The step that matters
Repeating the syrup soak over three to four days. Sugar must slowly penetrate the fruit to replace its water. Draining, reboiling and repouring the syrup each day gradually raises the sugar concentration, which helps the plums keep their shape and resist spoilage.
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.
