Why it works: Apple and sugar are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 16,478 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Crab Apple Preserves
Ingredients
Directions
Prepare the apples
Pick out nearly perfect crab apples, leaving the stems on.
Put them in a preserving kettle with enough warm water to cover.
Heat to boiling slowly and simmer until the skins break.
Drain and skin the apples, then extract the cores with a paring knife through the blossom ends.
Make the preserves
Weigh the apples and add 1½ lbs. of sugar and ½ cup of water for each pound of fruit.
Boil the water and sugar together until the scum ceases to rise.

Shared aroma: 1-octen-3-ol (mushroom, earthy).
Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red siberian crab apples
- Provide the fruit flavor and natural pectin that helps the preserves thicken and set.
- Sugar
- Adds sweetness and helps preserve the fruit by binding water and inhibiting spoilage.
The step that matters
Boil the water and sugar until the scum stops rising. Skimming off the foam that rises as the syrup boils removes impurities, so the syrup stays clear and the preserves look clean and bright.
