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
Grate the rinds of the Seville oranges on a fine grater.
Cut the oranges into quarters and separate the flesh from the rinds.
Remove the pips and loose inner skin from the flesh using a small spoon.
Soak the rinds in cold water and change the water after boiling for 20 minutes.
Once tender, drain the rinds and slice them thin.
Make and jar the marmalade
Combine 8 ounces of sliced rinds with 1 pound of pulp and juice and 1.5 pounds of sugar.
Boil the mixture quickly for 30 minutes, skimming off any foam.
Pour the marmalade into jars.

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 flavour and pectin.
- Finely powdered sugar
- Sweetens the marmalade and helps it set into a thick, spreadable gel when boiled.
The step that matters
Boil the mixture quickly for 30 minutes, skimming off any foam. Rapid boiling drives off water so the sugar and fruit pectin reach the concentration needed to set. Skimming removes foam so the marmalade stays clear and glossy.
