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 rind
Blanch the rinds of the oranges until soft, then soak them in cold water for a few minutes.
Drain and pound the rinds to a paste, then rub it through a sieve.
Weigh the paste and for each pound, use 1.5 pounds of sugar.
Cook the marmalade
Clarify and boil the sugar until the bubbles rise strongly to the surface.
Add the paste to the boiling sugar and stir continuously until the marmalade is done.
To check if it's done, take some between your thumb and finger; if it draws out like a thread, it's ready.

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
- Orange rinds
- Provide the bitter aroma and the pectin-rich body that sets the marmalade.
- Sugar
- Sweetens the marmalade and, when boiled down, helps it thicken and set.
The step that matters
Stirring the paste into the boiling sugar. Sugar syrup at a strong boil can scorch on the bottom of the pan if not stirred constantly, and the mixture must reach the thread stage to set properly.
