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

What each ingredient does

Apples
Provide the pectin and natural acid that let the juice set into jelly.
Sugar
Adds sweetness and, with boiling, helps the juice thicken and set.

The step that matters

Boil down the mixture until it reduces by half.. Boiling concentrates the juice and sugar so the pectin and acid can gel. Too little boiling leaves a runny jelly, while overboiling can make it stiff or cause sugar to crystallise.

Swap the apple

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

  1. Vanillafits better
  2. Apricotfits better
  3. Raisinfits better
  4. Applethe original

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