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

Seville oranges
Provide the bitter peel, pectin and acidity that give marmalade its flavour and set.
Sugar
Sweetens the marmalade and, when boiled, helps it thicken and set.
Cold water
Softens the orange halves and draws out bitterness during the overnight soak.

The step that matters

Boiling the sugar to the crackle stage. Sugar must be boiled to the right concentration so the marmalade sets when cooled. Too little boiling leaves it runny, and too much makes it hard and sticky.
