  2. Boil until the skin breaks.

  3. Remove each apple, skin them, and take out the seeds with a penknife.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Crab apples
Provide the fruit, pectin and tartness that give the preserve its body and flavor.
Sugar
Sweetens the preserve and, once dissolved, helps preserve the fruit and make it transparent.

The step that matters

Boil the apples in the syrup until transparent. Boiling too briskly can break the apples apart or darken them. Gentle simmering lets sugar slowly replace the water in the fruit, which is what makes it translucent and firm.

Swap the apple

How well each one fits the dish's main ingredients (crab, sugar):

  1. Raisinfits better
  2. Lemonfits better
  3. Vanillafits better
  4. 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.
