Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the butter and gravy, giving the sauce a rich, smooth body.
- Melted butter
- Adds fat and richness, carrying flavour and giving the sauce a silky texture.
- Thickened veal gravy
- Provides the savoury base and body of the sauce.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances the butter.
The step that matters
Adding the melted butter to the yolk mixture. Egg yolks thicken and emulsify with fat only when the butter is added gradually and warm enough to blend. Adding it too fast or too hot can split the sauce, leaving it greasy and grainy.
Swap the white pepper
How well each one fits the dish's main ingredients (asparagus, veal, egg, butter, lemon):
- Tarragonfits better
- Parsleyfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against asparagus, veal, egg, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
