Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chervil
- Adds a fresh, delicate herb aroma and flavor to the sauce.
- Garden cress
- Adds a peppery, fresh flavor and bright green colour.
- Tarragon
- Adds a distinctive aniseed-like aroma that defines the sauce's flavor.
- Burnet
- Adds a light, cucumber-like freshness and more green colour.
- Mayonnaise sauce
- Provides the creamy, fatty base that carries the herb flavors and gives body.
The step that matters
Stir the herb mixture into the mayonnaise sauce. Mayonnaise is an emulsion of oil and egg. Folding the herbs in gently, rather than beating hard, keeps the emulsion intact so the sauce stays smooth and does not turn thin or grainy.
Swap the tarragon
The recipe marks tarragon as optional. How well each one fits the dish's main ingredients (chervil, garden cress, sauce, vinegar):
- Capersfits about as well
- Tarragonthe original
- Parsleyfits less well
- Marjoramfits less well
