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: beta-damascenone (apple, rose).
Orange and sugar barely smell alike, yet cooks put them together in 19,212 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
- Oranges
- Provide the fruit pulp, bitter peel and pectin that give marmalade its body and tang.
- Sugar
- Sweetens and, with the fruit's pectin and acid, helps the mixture thicken and set.
The step that matters
Cook slowly for one hour. Sugar must dissolve fully before a long, gentle simmer; boiling too hard can scorch the sugar and darken the flavour, while too little cooking leaves the pectin unable to set the marmalade.
