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
Cut the oranges in half and remove the insides, discarding the pips and skin.
Wash the inside skin in a little water and add it to the pulp.
Boil the rinds in plenty of water for about 4 hours, changing the water once to reduce bitterness.
Cut the boiled rinds into small pieces.
Cook the marmalade
In a pot, combine the pulp, juice, and sugar, and boil for 30 minutes.
Add the pieces of rind and boil for an additional 4 to 5 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
- Oranges
- Supply the pulp, juice, and peel that give marmalade its bright citrus flavour and bitter edge.
- Lump sugar
- Sweetens the marmalade and, as it cooks down, helps it thicken and set.
The step that matters
Changing the water when boiling the rinds. Boiling the rinds for about 4 hours and changing the water once reduces the bitter compounds in the peel. Skipping the change leaves the marmalade noticeably more bitter.
