Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and juicy moisture of the salad.
- Hard-boiled eggs
- Add firm, mild protein texture and body to the salad.
- Raw egg
- Thickens the dressing as it cooks gently in the vinegar, binding it together.
- Vinegar
- Adds acidity that brightens the salad and balances the sweetness.
- Sugar
- Softens the sharpness of the vinegar and rounds out the flavor.
The step that matters
Combine the beaten raw egg with the vinegar. Raw egg can scramble or curdle if it meets acid without careful whisking. Whisking the egg thoroughly and adding it gradually keeps the dressing smooth.
Swap the tomato

- Capsicumfits better
