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 ↓
Sauce Bordelaise
Ingredients
Directions
Make the sauce
In a saucepan, combine the claret and shallots, and bring to a boil.
Add the Espagnole sauce and glaze, then simmer gently for about 25 minutes.
If the sauce is too thick, add a little stock; if too thin, boil with the lid off.
Skim well, then add the chopped herbs and season carefully.
Finish
The sauce should be thick enough to coat the back of a wooden spoon and run off again.
Do not strain this sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Espagnole sauce
- Forms the thick, savoury body of the sauce.
- Claret
- Adds acidity and wine flavour that reduces into the sauce.
- Glaze
- Adds concentrated meaty depth and body to the sauce.
- Shallot
- Contributes a mild, sweet aromatic base to the sauce.
The step that matters
Judging the thickness. Sauces thicken as they simmer and reduce, so adding too much stock or boiling too hard can throw off the balance. Checking that the sauce coats the back of a spoon and runs off cleanly shows it has reached the right concentration before serving.
Swap the parsley
How well each one fits the dish's main ingredients (sauce, shallot, gelatin, tarragon, chervil, pepper, sugar):
- Capersfits better
- Parsleythe original
- Fennelfits about as well
- Thymefits less well
Fit is the average pairing score against sauce, shallot, gelatin, tarragon, chervil, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
