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 Seville oranges in half, then slice them thinly, removing the pips.
Cook the marmalade
For every pound of oranges, add two pounds of sifted sugar and ½ cup of water to a preserving pan.
Set the pan over high heat and bring the mixture to a boil, stirring and skimming until it reaches a proper consistency.
To test, place a small amount on a saucer and cool it in cold water.
Pot and store
Fill pots with the marmalade, let it cool, then cover with white paper dipped in brandy.
Seal the pots with paper and white leather, and store in a dry place.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 pectin-rich pulp that give marmalade its flavour and set.
- Sifted sugar
- Sweetens the marmalade and helps it thicken and set as it cooks down.
The step that matters
Testing for proper consistency. Sugar and fruit pectin set only at a sufficient concentration and temperature, so undercooking leaves marmalade runny while overcooking makes it stiff. A cold saucer test shows whether it will gel as it cools.
