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.

What each ingredient does
- Oranges
- Supply the fruit, peel and pectin that help the marmalade set.
- Lump sugar
- Sweetens the marmalade and, at high concentration, helps it set into a jelly.
The step that matters
Boil until the syrup jellies. Setting depends on the sugar and pectin concentration reaching the gel point. Stopping early leaves the marmalade runny, while over-boiling darkens its flavour and can make it stiff.
