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 ↓
Clear Orange Marmalade
Ingredients
Directions
Prepare the fruit
Wash and wipe the orange rinds clean, then cut them into quarters.
Boil the rinds in a large quantity of water until tender, then drain them.
Scrape off the white skin and fibers from the rinds while they are still warm.
Pound the rinds to a paste and blend with the pulp and juice gradually to avoid lumps.
Add the strained water from the pips and pass through a net strainer or coarse sieve.
Cook the marmalade
Boil the mixture without sugar for 15 to 20 minutes.
Add half of the sugar and boil for 10 to 15 minutes, then add the remaining sugar.
Continue boiling for another 15 to 20 minutes until the marmalade is thick and clear.

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.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Seville oranges
- Provide the bitter peel, pulp and juice that give marmalade its characteristic flavor and natural pectin.
- Orange rinds
- Supply the bitter peel and pectin, and the pounded pieces give the marmalade its body and texture.
- Sugar
- Sweetens and, as it dissolves and concentrates, helps the marmalade set and keep.
The step that matters
Adding the sugar in stages. Sugar added to a boil at once can slow fruit softening and cause uneven setting. Adding half first, then the rest, keeps the boil steady and helps the mixture reach a clear, thick set without scorching.
