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

What each ingredient does

Eggs
Thicken the mixture as they set with gentle heat, giving the cream its body.
Sugar
Sweetens the cream and balances the sharpness of the lemon juice.
Lemons
Provide the acidity and aroma; the rinds flavour the water while it sits.

The step that matters

Cook over gentle heat while stirring continuously. Egg proteins set and thicken the cream, but high heat or stopping the stirring can make the eggs curdle or scramble. Gentle, constant stirring keeps the mixture smooth as it thickens.

Swap the lemon
