Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Made mustard
- Acts as an emulsifier, helping the oil and vinegar stay blended into a smooth, thick dressing.
- Olive oil
- Provides fat and body, forming the bulk of the dressing and giving it a rich mouthfeel.
- Vinegar
- Adds acidity and sharpness that balances the richness of the oil.
The step that matters
Add the oil slowly while stirring constantly. Oil and vinegar are normally immiscible. Adding the oil slowly, while stirring, breaks it into tiny droplets that the mustard can hold in suspension. Adding it too fast lets the droplets merge, so the dressing separates and stays thin and oily.
Swap the mustard
How well each one fits the dish's main ingredients (olive, vinegar, pepper):
- Capsicumfits better
- Tomatofits better
- Mustardthe original
- Cucumberfits about as well
Fit is the average pairing score against olive, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
