Why it works: Sugar and apple 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
Ingredients
Directions
Prepare the apples
Leave the stem on the crab apples.
Pierce the apples with a large needle.
Make the syrup
Make a syrup by dissolving the sugar in water until clear.
Add the apples to the syrup and boil for 30 to 40 minutes.
Carefully remove the apples and place them on a dish to cool.
Jar and serve
Once cooled, transfer the apples to jars and strain the hot syrup over them.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and apple 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
- Sugar
- Sweetens the preserves and, dissolved into syrup, helps preserve the fruit.
- Crab apples
- Provide the tart fruit that is cooked and preserved in the syrup.
The step that matters
Piercing the apples before boiling. Piercing the skins lets the syrup penetrate the flesh, so the fruit cooks evenly and absorbs sugar rather than staying firm on the outside. Skipping it can leave the centres underdone or the syrup poorly absorbed.
Swap the apple
How well each one fits the dish's main ingredients (sugar, crab):
- Raisinfits better
- Lemonfits better
- Vanillafits better
- Applethe original
Fit is the average pairing score against sugar, crab. Candidates are from the same food group and used in at least 100 recipes.
