Why it works: Parsley and tarragon 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 ↓
Ducks En Salmis
Ingredients
Directions
Prepare the duck
Cut the half-roasted ducks into legs, wings, and breast, placing them in one stewpan, and the backbone in another.
Stew the legs and wings gently in 1 cup of consommé until nearly dry.
Make the sauce
In the stewpan with the backbone, add the onion, ham, parsley, and 1 cup of consommé; bring to a boil.
Add 3 tablespoons of plain sauce and let it boil gently, stirring occasionally until thickened.
Strain the mixture through a fine sieve into the stewpan with the duck pieces; heat thoroughly.
Serve
Place the duck in a serving dish garnished with fried bread.
Stir in the egg yolk and cream into the sauce, pour it over the duck, and serve.
Before serving, add chopped tarragon, chervil, and tarragon vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ducks
- Provide the main meat, which is gently stewed until tender and flavourful.
- Egg yolk
- Thickens the sauce and gives it a smooth, rich texture when stirred in.
- Cream
- Adds richness and a silky mouthfeel to the finished sauce.
- Plain sauce
- Forms the base that thickens the consommé into a body-rich sauce.
- Consommé
- Supplies the clear, savoury liquid that cooks the duck and forms the sauce.
The step that matters
Stirring the egg yolk and cream into the sauce. Egg yolk can curdle or scramble if the sauce is too hot when it is added. Removing the sauce from direct heat before stirring in the yolk and cream keeps it smooth and thick.
Swap the onion
How well each one fits the dish's main ingredients (ham, parsley, sauce, egg, cream, bread, tarragon):
- Shallotfits better
- Mustardfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against ham, parsley, sauce, egg, cream, bread, tarragon. Candidates are from the same food group and used in at least 100 recipes.
