Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Quince Preserves
Ingredients
Directions
Prepare the quinces
Peel the quinces and cut them into round pieces, saving the peels and cores for jelly.
Place the quince pieces in a porcelain kettle and cover with cold water.
Boil until soft enough to pierce with a straw, then remove from water.
Make the syrup
In a separate pot, combine equal weight of sugar and water, and add the egg white.
Bring the syrup to a boil, skimming and straining it as soon as it boils.
Cook the preserves
Add the quinces to the syrup and cook until the syrup thickens.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Quinces
- Provide the fruit body and pectin that help the preserve set as it cooks.
- Sugar
- Sweetens the preserve and, at high concentration, helps it thicken and keep.
- Egg white
- Binds impurities into a foam that can be skimmed off, clarifying the syrup.
The step that matters
Skimming and straining the syrup as it boils. Egg white coagulates and rises with impurities as the syrup boils. Removing that foam early keeps the syrup clear and prevents off flavours. Skim promptly, since letting it sit can cloud the final preserve.
Swap the quince
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Quincethe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
