Ingredients
Directions
Stir together the chili vinegar and French vinegar in a bowl to taste.
Gradually add olive oil in small portions while stirring briskly until the mixture resembles custard.
Mix in any optional ingredients as desired. If using garlic, ensure it is a very small piece to avoid overpowering the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Forms the body of the dressing and carries its richness and mouthfeel.
- Strong chili vinegar
- Provides the sharp acidity and heat that defines the dressing.
- French vinegar
- Adds acidity that balances the oil and rounds out the sharpness of the chili vinegar.
The step that matters
Adding the olive oil. Oil must be added slowly in small portions while stirring briskly so it emulsifies into the vinegar. Adding it too fast makes the mixture separate instead of thickening into a smooth, custard-like texture.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (vinegar, olive, sauce, tarragon, garlic):
- Mustardthe original
- Shallotfits about as well
- Tomatofits about as well
- Chivefits less well
Fit is the average pairing score against vinegar, olive, sauce, tarragon, garlic. Candidates are from the same food group and used in at least 100 recipes.
