Why it works: Tarragon and chervil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 824 recipes. Both carry estragole, which smells anise, licorice. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Place the fish on a greased baking tray and bake for about 10 minutes or until cooked through.
Make the sauce
In a saucepan, reduce the tarragon vinegar.
Add the white sauce to the reduced vinegar and mix well.
Stir in the chopped herbs and season with salt and pepper.
Serve
Once the fish is done, transfer it to a serving dish and pour the sauce over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sole
- Forms the main body of the dish and cooks to flaky, tender fish in the oven.
- White sauce
- Provides a creamy, rich coating that adds moisture and body to the fish.
- Tarragon vinegar
- Adds sharp acidity that cuts the richness of the sauce and gives it a bright flavour.
The step that matters
Reduce the tarragon vinegar. Reducing concentrates the vinegar and mellows its sharpness, so the sauce tastes balanced rather than harsh when it is combined with the white sauce.
Swap the parsley
How well each one fits the dish's main ingredients (sauce, tarragon, vinegar, chervil, pepper):
- Capersfits better
- Parsleythe original
- Fennelfits about as well
- Marjoramfits less well
Fit is the average pairing score against sauce, tarragon, vinegar, chervil, pepper. Candidates are from the same food group and used in at least 100 recipes.
