Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Preserved Barberries
Ingredients
Directions
Make the syrup
Drop the stemmed barberries into boiling molasses (or a mixture of half molasses and half sugar).
Boil for 10 to 15 minutes.
Skim out the barberries.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barberries
- Provide the tart fruit flavor and hold their shape while cooking in the syrup.
- Molasses
- Forms the dark, thick syrup that sweetens and gives the preserves their deep flavor.
- Sugar
- Adds sweetness and helps thicken the syrup as an optional partial replacement for molasses.
Swap the apple
The recipe marks apple as optional. How well each one fits the dish's main ingredients (lemon, molasses, sugar):
- Orangefits better
- Raisinfits better
- Vanillafits better
- Applethe original
Fit is the average pairing score against lemon, molasses, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
