Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up the bulk of the sauce and give it a crisp, fresh texture.
- Onions
- Add savory depth and body as they soften in the sauce.
- Mustard seed
- Provides the sharp, pungent mustard flavor of the sauce.
- White sugar
- Adds sweetness that balances the sharpness of the vinegar and mustard.
- Vinegar
- Provides acidity and the cooking liquid that softens the vegetables and sharpens the sauce.
- Coleman's mustard
- Adds extra heat and pungency to the sauce.
The step that matters
Cook the mixture well in vinegar. Mustard's pungency develops when ground seed meets liquid and mellows with heat, so a thorough cook in vinegar softens the sharp bite. Heat and acid also soften the vegetables, so the sauce tastes balanced rather than raw.
