Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks emulsify the oil and lemon juice into a thick dressing, and whites add lightness.
- Olive oil
- Fat that blends with the yolks to give the dressing body and richness.
- Lemon
- Adds acidity that brightens the dressing and balances the fat.
- Whipped cream
- Adds richness and a light, airy texture.
The step that matters
Slowly add the olive oil and lemon juice while beating. Adding the oil too quickly can overwhelm the egg yolks, so they cannot hold it in suspension and the dressing breaks and stays thin. Adding it slowly while beating lets the yolk proteins coat each droplet, which builds a thick, stable emulsion.
Swap the lemon
How well each one fits the dish's main ingredients (egg, cream, sugar, olive):
