Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Adds bulk and a crisp texture to the finished sauce.
- Vinegar
- Provides the sharp acidity that defines the sauce and helps preserve it.
- Brown sugar
- Adds sweetness and balances the acidity of the vinegar.
- Mustard seed
- Contributes a pungent, slightly bitter aroma and flavor.
- Celery seed
- Adds an earthy, aromatic flavor that rounds out the sauce.
The step that matters
Sprinkle with salt and let stand overnight. Salt draws water out of the chopped vegetables through osmosis, softening them and concentrating flavor. Skipping or shortening this rest leaves the vegetables wetter and crunchier, which changes the sauce's texture.
Swap the onion
