Directions
Prepare the dressing
Pare and slice the tomatoes, then place them in a salad bowl.
In a separate bowl, mix the salt, pepper, sugar, and mustard into a paste with the oil.
Gradually beat in the vinegar until well combined.
Add the raw egg yolk and mix thoroughly.
Serve
Pour the dressing over the tomatoes and set on ice until ready to serve.

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.
- Raw egg yolk
- Emulsifies the oil and vinegar so the dressing stays smooth and creamy.
- Made mustard
- Helps bind the oil and vinegar into a stable emulsion and adds a sharp flavor.
- Oil
- Adds fat and richness, carrying flavor and giving the dressing body.
- Vinegar
- Adds acidity that brightens the dressing and balances the fat and sweetness.
The step that matters
Adding the vinegar gradually. Beating vinegar into the oil-mustard paste slowly lets the mixture emulsify. Adding it all at once can cause the dressing to separate and turn greasy.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, sugar, mustard, vinegar, egg):
- Horseradishfits better
- Capsicumfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against pepper, sugar, mustard, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
