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
Score the peel of the oranges with a sharp knife and remove it in quarters, being careful not to pierce the inner fruit.
Boil the skins until tender enough to pierce with a pin.
Scrape off all tough white pulp from the fruit, divide it into sections, and remove the seeds.
Once the skins are tender, scrape out the white spongy part and cut the skins into thin chips about 1 inch long.
Make the marmalade
Clarify the sugar, then add the chips and fruit to the boiling sugar, and let it boil quickly for 20 minutes.

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
- Peel supplies bitterness and pectin, while the fruit provides body and tartness for the set.
- Sugar
- Sweetness, and with the fruit's pectin and acid, helps the marmalade gel as it boils.
The step that matters
Boiling the chips and fruit in the sugar for 20 minutes. Boiling quickly concentrates the sugar and releases pectin from the peel and seeds, which sets the marmalade. Too little boiling leaves it runny, while over-boiling can darken and toughen the flavour.
