Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the bulk of the fruit that softens and becomes tender during cooking.
- Sugar
- Sweetens the syrup and preserves the apples, helping keep them firm and clear.
- Water
- Dissolves the sugar to form the syrup the apples cook in.
The step that matters
Cook until the mixture is clear. Sugar syrup slowly penetrates the fruit and makes it translucent; stopping early leaves the apples opaque and less preserved. Cooking too hard can break the quarters apart.
Swap the clove
The recipe marks clove as optional. How well each one fits the dish's main ingredients (apple, sugar, lemon):
- Cinnamonfits better
- Gingerfits better
- Nutmegfits about as well
- Clovethe original
Fit is the average pairing score against apple, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
