Sugar and apple 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

Loaf sugar
Sweetens the marmalade and, when boiled thick, helps it set into a jelly.
Orange rind
Adds bitter aroma and body from the peel, which is cooked until tender and beaten fine.
Orange pulp
Supplies fruit flesh and juice, adding flavour and pectin that help the marmalade gel.
Apple liquor
Adds liquid and extra pectin-rich fruit character to help the marmalade jellify.

The step that matters

Boil until the syrup is very thick. Stirring carefully matters because sugar syrup scorches easily on the bottom of the pan. The syrup must reach a dense concentration so the marmalade can set into a jelly once the fruit is added and boiled gently.

Swap the orange

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

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

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