Why it works: Quince and apple work together. They rank in the top 1% of all ingredient pairs, and cooks put them together in 506 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. The science ↓
Delicious Quince Jelly
Ingredients
Directions
Prepare the fruit
Place chopped quinces and apples in a preserving pan and cover with water.
Cover the pan and simmer for several hours.
Drain the mixture in a colander overnight.
The next morning, strain the juice through a jelly bag.
Make the jelly
Measure the juice and add an equal amount of sugar, then boil until it turns pink.
Test the consistency on a saucer; when thickened, dip the geranium sprigs in the jelly and swirl them.
Remove the jelly from heat and pour it into glasses.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Quinces
- Provide natural pectin and tart flavour that help the jelly set.
- Apples
- Add additional pectin, helping the juice gel firmly when cooked with sugar.
- Sugar
- Sweetens the jelly and, at high concentration, helps it set by binding water.
The step that matters
Testing the set on a saucer. Boiling must stop once the jelly thickens. Overcooking can make it stiff and dull, while undercooking leaves it runny, so a cold saucer test shows when it has reached setting point.
