Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Forms the base of the sauce, adding richness and body that carries the flavour.
- Tarragon vinegar
- Adds sharp acidity and a sour bite that balances the oil.
- Onion vinegar
- Contributes further acidity and a mild savoury aroma to the sauce.
- Brown sugar
- Adds a little sweetness that rounds out the sharpness of the vinegars.
The step that matters
Gradually add the vinegars while stirring. Oil and vinegar are immiscible, so adding the vinegar slowly while stirring breaks it into small droplets. This creates a temporary emulsion, which keeps the sauce smooth rather than separating into layers.
Swap the onion
How well each one fits the dish's main ingredients (olive, tarragon, vinegar, pepper, sugar):
- Capsicumfits better
- Mustardfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against olive, tarragon, vinegar, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
