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 ↓
Preserved Crab Apples
Ingredients
Directions
Prepare the apples
Wash the crab apples.
Cover the bottom of a preserving kettle with grape leaves.
Place the apples in the kettle.
Add a little water.
Cover the kettle closely.
Simmer gently until the apples turn yellow.
Remove the apples and cool them on a large dish.
Pare and core the apples.
Cook the apples
Return the apples to the kettle with fresh vine leaves and a little water.
Hang the apples over the fire until they turn green, but do not let them boil.
Make the syrup and preserve
Dissolve 1 pound of sugar in just enough water.
Boil the sugar solution and skim the syrup.
Add the apples to the syrup.
Boil until the apples are clear and tender.
Transfer the apples to jars.
Pour the syrup over the apples.
Tie the jars up when cold.

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
- Crab apples
- The main fruit; its natural pectin and acidity help the preserve hold its shape and set.
- Loaf sugar
- Sweetens the fruit and, as a thick syrup, helps preserve it and keep it firm.
- Fresh vine leaves
- Lie under and around the apples, adding a subtle aroma and flavor as they cook.
The step that matters
Keep the apples from boiling while they turn green. Boiling at this stage can break down the fruit's cell structure, leaving it soft and mushy. Gentle heat lets the apples soften and firm evenly while keeping their shape for the later syrup stage.
Swap the apple
How well each one fits the dish's main ingredients (crab, sugar):
- Raisinfits better
- Lemonfits better
- Vanillafits better
- Applethe original
Fit is the average pairing score against crab, sugar. Candidates are from the same food group and used in at least 100 recipes.
