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 ↓
Seville Orange Marmalade
Ingredients
Directions
Prepare the oranges
Squeeze the juice from the Seville oranges.
Boil the peels in plenty of water until very tender.
Put the peels in cold water and scrape out the pulp without breaking the peel.
Cut the peel into very fine strips or pass it through a machine.
Make the marmalade
Strain the juice and boil it with a pound of loaf sugar for every pint and pound of peel until it jellies on a saucer.
Add the fine-cut peel and boil briefly in the syrup.

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
- Provide the bitter peel and juice that give marmalade its characteristic sharp flavour and natural pectin.
- Loaf sugar
- Sweetens the bitter juice and, with the acid and pectin, helps the mixture set into a jelly.
The step that matters
Boiling the juice and sugar until it jellies. Setting depends on pectin, acid and sugar reaching the right concentration. Underboiling leaves the marmalade runny, while overboiling can make it dark and stiff. Testing on a cold saucer shows when it is ready.
