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
Combine sliced oranges and cold water in a bowl and let stand overnight.
Make the marmalade
Boil the mixture gently for about 45 minutes until the oranges are soft.
For each pound of the orange mixture, add 1 lb 3 oz of granulated sugar.
Boil until the mixture is clear and the juice thickens, about one hour.
Seal
Seal the marmalade while it is still hot.

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, aroma, and natural pectin that helps the marmalade set.
- Granulated sugar
- Sweetens the marmalade and, with boiling, thickens it into a spreadable set.
The step that matters
Boil until the juice thickens and turns clear. The mixture must reach setting point, where sugar, acid and pectin form a gel as water evaporates. Stopping early leaves it runny, while overboiling darkens the flavour and can make it stiff.
