Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Forms the bulk of the sauce and supplies its crisp, fresh texture and vegetal flavor.
- Coarse sea salt
- Draws water out of the celery and onion, softening them and concentrating their flavor.
- Good vinegar
- Provides acidity that gives the sauce its tang and helps preserve the mixture.
- Mustard seed
- Adds sharp, pungent heat and a distinctive mustard flavor to the sauce.
- Ground mustard
- Contributes further pungency and mustard flavor, blending with the mustard seed.
The step that matters
Draining the salted celery and onion. Salt pulls moisture out of the vegetables, so draining them well keeps the sauce from becoming watery and thins its vinegar balance. Skipping or rushing this step leaves excess liquid diluting the flavor.
Swap the onion
