Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks bind the oil and vinegar into a smooth, thick sauce and add richness.
- Salad oil
- Provides fat that gives the sauce body and a smooth, rich mouthfeel.
- Vinegar
- Adds sharp acidity that brightens the flavour and balances the fat.
- Mustard
- Helps hold the oil and yolk mixture together as a stable emulsion and adds sharpness.
- Tomato catsup
- Adds sweetness, acidity and colour to the sauce.
The step that matters
Pulverize the yolks well. Egg yolk is the emulsifier that holds oil and vinegar together. If the yolks stay in lumps, the oil will not disperse evenly, and the sauce will look greasy and separate.
Swap the tomato
How well each one fits the dish's main ingredients (egg, mustard, pepper, vinegar):
- Horseradishfits better
- Capsicumfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against egg, mustard, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
