Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide proteins that emulsify and thicken the sauce as they set.
- Butter
- Adds fat and richness, giving the sauce a smooth, creamy body.
- Lemon juice
- Adds acidity that brightens the flavor and balances the richness of the butter.
- Vinegar
- Adds acidity and sharpness that cuts through the fat and rounds out the flavor.
- Dry mustard
- Contains natural emulsifiers that help hold the fat and liquid together.
The step that matters
Slowly add the melted butter while stirring continuously. Adding fat too quickly before the egg proteins are dispersed can break the emulsion, causing the sauce to separate and turn greasy instead of smooth and thick.
Swap the ginger
How well each one fits the dish's main ingredients (egg, lemon, butter, vinegar, mustard, sugar, pepper):
- Tarragonfits better
- Dillfits better
- Parsleyfits better
- Gingerthe original
Fit is the average pairing score against egg, lemon, butter, vinegar, mustard, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
