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

What each ingredient does

Egg yolks
Thicken the sauce and add richness as they set gently with heat.
Butter
Adds fat for a smooth, rich texture and mouthfeel.
Flour
Thickens the sauce so it holds together and coats food.
Lemon juice
Adds acidity that brightens the rich, buttery flavor.

The step that matters

Keep the heat low and do not let it boil. Egg yolks thicken at gentle heat but curdle when overheated, leaving a grainy sauce. Stirring constantly spreads heat evenly and prevents this.
