Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the main body of the salad and supply moisture and juicy texture.
- Oil
- Adds fat and richness, carrying flavour and softening the sharpness of the vinegar.
- Vinegar
- Provides acidity that brightens the dressing and balances the sweetness.
- Sugar
- Adds sweetness that offsets the acidity of the vinegar.
- Prepared mustard
- Adds sharpness and helps the oil and vinegar emulsify into a smoother dressing.
The step that matters
Gradually whisk in the vinegar until combined. Adding vinegar slowly while whisking lets the oil and vinegar form a temporary emulsion, helped by the mustard, so the dressing stays smooth rather than separating into layers.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, mustard, pepper, vinegar):
- Horseradishfits better
- Capsicumfits better
- Radishfits better
- Tomatothe original
Fit is the average pairing score against sugar, mustard, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
