Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Adds richness and a smooth, silky body to the set mixture.
Sugar
Sweetens the jam and, with the heat, thickens it into a spreadable texture.
Eggs
Egg yolks and whites thicken the mixture as they cook, giving it a custard-like set.
Lemons
Juice and rind supply the sharp acidity and bright aroma that define the flavour.

The step that matters

Stir continuously and let it boil gently until it resembles honey. Egg proteins can scramble or curdle if the mixture overheats or is left unstirred, so constant stirring and gentle heat keep it smooth while it thickens.
