Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yellow mustard
- Provides the main body, sharp pungency and flavour of the condiment.
- Vinegar
- Adds acidity and sharpness that balances the mustard's heat.
The step that matters
Thickening the boiling vinegar with the mustard paste. Adding the paste to boiling liquid can cause lumps if it is not blended in evenly. The 15-minute cook time lets the mixture thicken smoothly and mellows the raw, sharp heat of the mustard.
