Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard boiled eggs
- Yolks mashed into the dressing add richness and body; whites add texture to the salad.
- Olive oil
- Fat that emulsifies with the yolks to give the dressing a smooth, creamy body.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the yolks and oil.
- Tomatoes
- Provide moisture and fresh, slightly acidic flavor to the salad.
- Celery
- Adds crisp texture and a fresh, mildly savory note.
The step that matters
Stir the yolks smooth before adding the oil and vinegar. Mashing the yolks thoroughly and blending the dressing until smooth lets the oil and vinegar combine evenly with the yolks, which act as an emulsifier. Lumps or unblended oil make the dressing separate and taste uneven.
