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 fresh flavour.
- Egg
- Emulsifies the oil and vinegar, helping the dressing thicken and hold together.
- Salad oil
- Adds richness and carries flavour, and when emulsified gives the dressing body.
- Mustard
- Acts as an emulsifier that helps keep the oil and vinegar blended, and adds sharpness.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil.
The step that matters
Adding the oil a few drops at a time. Oil added too quickly will not emulsify with the seasonings and may separate. Adding it slowly lets the mustard and egg hold tiny oil droplets suspended, giving a smooth, stable dressing.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, mustard, egg, vinegar):
- Horseradishfits better
