Lemon and sugar 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

Seville oranges
Their peel and seeds are rich in pectin, which helps the marmalade set.
Common oranges
Their pulp and peel add bulk, body and sweet-bitter citrus flavour.
Lemons
Their acidity and pectin support setting and brighten the flavour.
Sugar
Sweetens the marmalade and, when concentrated by boiling, helps it set and keeps it preserved.

The step that matters

Boil for 20 minutes. Boiling concentrates the sugar and draws out pectin from the peel and pulp. Too little boiling leaves the marmalade runny, while too much can make it stiff and dark.
