Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mayonnaise
- Provides the fat and creamy base that gives the sauce its body and moisture.
- Mustard
- Adds sharp tang and helps hold the emulsified sauce together.
- Shallot
- Adds a mild, sharp onion-like aroma and bite.
The step that matters
Slowly heat the mixture over low heat.. Mayonnaise is an emulsion of oil and egg. Strong or fast heat can cause the egg proteins to tighten and the oil to separate, leaving the sauce greasy and grainy. Gentle, slow heating keeps it smooth.

Fit is the average pairing score against mustard, shallot. 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).
