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

What each ingredient does

Eggs
Thicken as they cook gently, giving the mixture its body and set.
Butter
Adds fat for a smooth, rich texture and mouthfeel.
Sugar
Adds sweetness and balances the sharpness of the lemon.
Lemon
Supplies acidity and bright aroma from the juice and grated rind.

The step that matters

Stir constantly over low heat. Eggs set when heated, so high heat or stopping to stir can scramble them and leave lumps. Gentle heat with constant stirring thickens the mixture evenly into a smooth, spreadable curd.

Swap the lemon
