Why it works: Tarragon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,563 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Fillets of Beef a LA Bearnaise
Ingredients
Directions
Prepare the fillets
Prepare the fillets, then dip them in beaten egg and coat with bread crumbs.
Fry the fillets in 2 tablespoons of hot butter until golden, then drain on paper towels.
Make the Béarnaise sauce
For the Béarnaise sauce, finely chop the shallot and combine it with the tarragon vinegar in a saucepan; boil until the vinegar evaporates.
Add the white sauce and egg yolks to the shallot mixture, cooking while stirring until thick.
Remove from heat and stir in the remaining butter in small pieces, then add the parsley.
Serve
Place the sauce in the center of the fillets, pour the brown sauce around, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef fillets
- Form the main body of the dish, cooked to golden under the crumb coating.
- Bread crumbs
- Form a crisp, golden coating on the outside of the fillets when fried.
- Egg yolks
- Thicken the sauce as they cook with the shallot mixture, giving it a rich, smooth body.
- Butter
- Adds richness and flavour to the frying and finishes the sauce for a silky texture.
- Tarragon vinegar
- Provides acidity and aromatic tarragon flavour, reduced to concentrate the sauce base.
The step that matters
Cooking the egg yolk sauce. Egg yolks thicken when gently heated but can scramble if overheated. Cook while stirring over low heat, then remove from heat before adding the butter so the sauce stays smooth.
Swap the parsley
How well each one fits the dish's main ingredients (beef, sauce, butter, egg, bread, tarragon, vinegar):
- Capersfits about as well
- Parsleythe original
- Nutmegfits less well
- Marjoramfits less well
Fit is the average pairing score against beef, sauce, butter, egg, bread, tarragon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
