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.

    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

Crab apples
Provide the fruit itself, along with natural pectin that helps the preserves set.
Sugar
Sweetens the fruit and, at this concentration, helps preserve it and firm its texture.

The step that matters

Boil the cored apples until tender. Overcooking breaks the fruit down into mush. The sugar syrup gradually draws water out of the apples, so timing the boil controls both texture and how much the fruit softens.

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.
