Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apple
- Adds crisp texture and natural sweetness to the salad.
- Celery
- Provides crisp, crunchy texture and fresh body to the salad.
- Egg yolk
- Emulsifies the olive oil into the dressing, giving it a thick, creamy texture.
- Olive oil
- Adds fat and richness to the dressing as it emulsifies with the yolk.
The step that matters
Slowly add the olive oil drop by drop while stirring. Oil must be added gradually so the egg yolk can disperse it into tiny droplets. Adding it too fast breaks the emulsion, leaving a greasy, separated dressing instead of a smooth, thick one.
Swap the apple
How well each one fits the dish's main ingredients (celery, mustard, pepper, egg, sugar, olive):
