The flavor team
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
- Sliced oranges
- Provide the fruit, pectin and bitter peel that give marmalade its flavor and set.
- Sugar
- Sweetens the marmalade and helps it set to a gel as it cooks.
The step that matters
Testing for a gel. Marmalade sets only when enough pectin, acid and sugar are concentrated by boiling. Testing on a chilled plate shows whether the gel point has been reached, so stopping too early leaves it runny and overcooking can make it stiff and sugary.
