Why it works: Orange and sugar are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 19,212 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Orange Marmalade
Ingredients
Directions
Prepare the oranges
Boil the oranges until tender enough for a pin to pierce the skin.
Grate half of the oranges to reduce bitterness.
Cut the boiled oranges in half.
Remove all the seeds.
Scoop out the pulp.
Cut the skins into thin strips.
Make the marmalade
Dissolve the sugar in 1½ pints of water in a preserving jar and boil for 20 minutes.
Skim the syrup well until clear.
Add the pulp and strips of peel to the syrup and boil for 15 minutes.

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
- Seville oranges
- Their peel and pulp supply the bitter flavour and pectin that help the marmalade set.
- Lump sugar
- Sweetens the marmalade and, as it concentrates, helps it set and keeps it preserved.
- Water
- Dissolves the sugar into a syrup that the fruit cooks in.
The step that matters
Skim the syrup well until clear. Skimming removes foam and cloudy particles from the dissolved sugar, so the finished marmalade looks clear rather than murky.
