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

What each ingredient does

Flour
Starch thickens the sauce as it heats in the boiling water.
Butter
Adds richness and a smooth, silky mouthfeel to the sauce.
Sugar
Provides sweetness that balances the sharpness of the lemon.
Lemon juice
Adds acidity that brightens the sauce and balances the sugar.
Lemon peel
Adds aromatic oils that give the sauce its lemon fragrance.

The step that matters

Let it cool slightly, then stir in the beaten egg.. If the sauce is still very hot, the egg proteins can set in lumps and scramble. Cooling slightly lets the egg blend in smoothly.

Swap the lemon
