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

What each ingredient does

French mustard
Adds sharp flavour and helps emulsify the oil into the sauce.
Oil
Forms the body of the sauce as it is whisked in slowly.
French vinegar
Adds acidity that brightens the sauce and thins it when too thick.
Shallots
Add a mild, sharp onion flavour.

The step that matters

Stirring in the oil drop by drop. Adding oil slowly lets the droplets disperse and bind with the mustard and vinegar, forming a stable emulsion. Adding it too fast can split the sauce into separated oil and liquid.

Fit is the average pairing score against shallot, chervil, tarragon, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
