Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and thicken the dressing into a smooth, rich body.
- Olive oil
- Provides the fat that gives the dressing its richness and body.
- Dry mustard
- Helps stabilize the emulsion and adds a sharp, pungent flavor.
- Thick sweet cream
- Adds moisture and richness, softening the dressing's texture.
- Vinegar
- Adds acidity that brightens the dressing's flavor.
The step that matters
Slowly add the olive oil while beating continuously. Oil added too fast cannot be dispersed into the egg yolks, so the emulsion breaks and the dressing stays thin and separated. Egg yolk lecithin holds the oil droplets in suspension only when they are added gradually.
Swap the mustard
How well each one fits the dish's main ingredients (egg, olive, sugar, pepper, cream, vinegar):
- Capsicumfits better
- Mustardthe original
- Spinachfits about as well
- Cucumberfits about as well
Fit is the average pairing score against egg, olive, sugar, pepper, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
