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 in enough water to cover them for 1 hour.
Strain the oranges through a sieve and set aside.
Quarter the oranges and scrape out the pulp and juice, discarding the skins, films, and seeds.
Make the marmalade
Combine the pulp and juice with the sugar in a pan.
Boil the mixture for 4 hours, skimming off any foam.
Store
Pour the marmalade into pans for storage.

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
- Pectin and acid in the fruit help the marmalade set, while the peel adds bitterness.
- Sugar
- Sweetens the marmalade and, with the fruit's pectin and acid, helps it set and keep.
The step that matters
Boiling the mixture for 4 hours. A long boil concentrates the sugar and fruit so pectin and acid can form a gel. Undercooked marmalade stays runny, and skimming the foam keeps the finished set clear.
