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.

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

Apples
Provide pectin and acid, which help the juice set into a jelly.
Sugar
Sweetens the jelly and helps it set firm when boiled with the juice.
Grated pineapple
Adds its flavour and fruit body to the jelly.

The step that matters

Boiling the juice with sugar. Sugar and acid must reach a rolling boil long enough for pectin to set the jelly. Undercooked jelly stays runny, while overcooking can make it stiff and dull.

Swap the pineapple

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

  1. Pearfits better
  2. Vanillafits better
  3. Apricotfits better
  4. Pineapplethe original

Fit is the average pairing score against apple, sugar. Candidates are from the same food group and used in at least 100 recipes.
