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 give it a rich, smooth body as they set with gentle heat.
- Butter
- Adds fat for a silky texture and rich flavour.
- Fish broth
- Forms the liquid base that carries the other ingredients.
- Lemon juice
- Adds acidity that brightens the rich sauce.
- Tarragon vinegar
- Adds sharp acidity and a faint aniseed aroma.
The step that matters
Stir constantly until the mixture boils. Egg yolks thicken when heated, but they can scramble if the heat is uneven or they sit still. Constant stirring spreads the heat evenly so the sauce becomes smooth and thick rather than grainy.
Swap the white pepper
How well each one fits the dish's main ingredients (fish, butter, egg, tarragon, vinegar, lemon):
- Parsleyfits better
- Capersfits better
- Dillfits better
