Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw egg yolks
- Emulsifiers that bind the oil and vinegar into a smooth, stable sauce.
- Salad oil
- Supplies the fat that gives mayonnaise its rich body and thick texture.
- Mustard
- Helps stabilise the emulsion and adds a sharp, tangy flavour.
- Tarragon vinegar
- Adds acidity and aromatic flavour that brightens the rich oil and yolks.
- Common vinegar
- Adds acidity that balances richness and sharpens the overall flavour.
The step that matters
Gradually add the salad oil drop by drop while stirring. Oil must be dispersed into the yolk mixture in tiny droplets so the egg proteins can coat them. Adding it too fast breaks the emulsion, leaving the sauce thin and oily instead of thick.
Swap the tarragon
How well each one fits the dish's main ingredients (egg, mustard, sugar, vinegar):
- Tarragonthe original
- Capersfits about as well
- Dillfits less well
- Cinnamonfits less well
Fit is the average pairing score against egg, mustard, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
