Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard
- Emulsifies the oil and vinegar, helping the dressing stay blended instead of separating.
- Vinegar
- Provides the acidity that gives the vinaigrette its sharp, bright flavour.
- Oil
- Adds fat that softens the acidity and carries flavour across the palate.
The step that matters
Slowly mixing in the oil. Adding the oil gradually while mixing breaks it into small droplets suspended in the vinegar. Pouring it in all at once lets the oil separate out, so the dressing stays blended only if the oil goes in slowly.
Swap the mustard
How well each one fits the dish's main ingredients (pepper, vinegar):
- Capsicumfits better
- Mustardthe original
- Cabbagefits about as well
- Cucumberfits less well
Fit is the average pairing score against pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
