Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify with the butter to thicken the sauce into a smooth, rich texture.
- Butter
- Adds richness and body, setting into a silky emulsion with the yolks.
- Shallot
- Adds a mild aromatic onion flavour as it cooks down with the vinegar.
- Vinegar
- Adds acidity that sharpens the flavour, reduced to concentrate it.
The step that matters
Adding the butter to the yolks. Butter must be added slowly, a little at a time, while stirring. Adding it too fast or with the sauce too hot can cause the yolks to scramble or the emulsion to break and separate.
Swap the shallot
How well each one fits the dish's main ingredients (butter, tarragon, vinegar, egg):
- Shallotthe original
- Mustardfits about as well
- Chivefits less well
- Cucumberfits less well
Fit is the average pairing score against butter, tarragon, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
