Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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

Oranges
Provide the bitter peel and pectin that give marmalade its body and characteristic flavour.
Granulated sugar
Sweetens the marmalade and, when boiled, helps it thicken and set.
Lemons
Add acidity and extra pectin, brightening the flavour and supporting setting.

The step that matters

Boil until thickened. Sugar and fruit pectin set only at a sufficiently high concentration, so the mixture must be boiled long enough to thicken. Stopping too early leaves a runny marmalade, while overcooking can make it stiff.
