Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard
- Supplies the main sharp, pungent flavor of the sauce.
- Vinegar
- Adds acidity that gives the sauce its tangy bite.
- Butter
- Adds fat that rounds the flavor and softens the texture.
- Sugar
- Balances the sharpness of the vinegar and mustard.
The step that matters
Cook the mixture on the stove for 3-4 minutes, stirring constantly.. Constant stirring spreads heat evenly so the mixture does not scorch on the bottom of the pan or form lumps while it thickens. Stopping early leaves the sauce thin, and overheating can make the butter separate.
