Why it works: Grape and quince work together. They rank in the top 8% of all ingredient pairs, and cooks put them together in 96 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Grape and Quince Jelly
Ingredients
Directions
Prepare the juice
Cut the quinces, removing all seeds, and cook them for 20 minutes.
Strain the cooked quinces and grapes together to extract the juice.
Make the jelly
Place the juice on the stove and bring it to a boil, skimming off any scum that forms for 15 minutes.
Preheat the oven and heat the sugar.
Add 1 pound of sugar for every pint of juice and boil for 10 minutes until ready for jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Quinces
- Their natural pectin and acidity help the juice set into a firm jelly.
- Grapes
- Supply most of the juice and the main fruit flavor of the jelly.
- Sugar
- Helps the jelly set and preserves it, while adding sweetness.
The step that matters
Boiling the juice with sugar. Sugar, pectin and acid only set when the mixture is concentrated by boiling. Stopping too early leaves the jelly runny, while boiling too long can make it dark and stiff.
Swap the grape
How well each one fits the dish's main ingredients (quince, sugar):
- Vanillafits better
- Pearfits better
- Applefits better
- Grapethe original
Fit is the average pairing score against quince, sugar. Candidates are from the same food group and used in at least 100 recipes.
