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 fruit
Peel the oranges and squeeze out the pulp and juice, removing all the seeds.
Boil the orange peel (cut into quarters) until tender, then scrape the inside clean.
Cut the boiled peel into very thin slices about an inch long.
Make the marmalade
Weigh the juice, pulp, and boiled peel, then add an equal weight of broken lump sugar.
Boil the mixture for 30 minutes, carefully removing any scum.
Pot and seal
Pour the marmalade into pots and seal them once completely cool.

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
- Peel supplies bitterness and pectin, while juice and pulp give the marmalade its body and set.
- Broken lump sugar
- Sugar sweetens the marmalade and, with the fruit's pectin, helps it set into a firm spread.
The step that matters
Boil the mixture for 30 minutes, removing scum. Boiling must be sustained long enough for the sugar to concentrate and the pectin to set the marmalade. Skimming off scum keeps the finished spread clear and clean-tasting.
