Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Eels À LA Tartare
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the eels
Skin and clean the eels, then cut off their heads.
Tie the eels in a round shape.
Make the sauce
Melt the butter in a saucepan.
Add the sliced carrots, onions, parsley, and bay leaf; fry until softened.
Add the white wine and season with salt and pepper; cook until the sauce is done.
Strain the sauce through a fine sieve and return it to the pan.
Stew, coat and bake
Add the tied eels to the sauce; stew until cooked through.
Moisten the eels with the sauce.
Sprinkle the eels with bread crumbs.
Moisten the eels again with the beaten egg yolks, seasoned with salt and pepper.
Sprinkle the eels with bread crumbs a second time.
Broil the eels over low heat or place them in the oven at 300°F (150°C) until golden brown.
Serve the eels on a plate with the sauce à la tartare poured around them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Main protein; they are stewed until cooked through and then browned.
- Butter
- Fat that softens the vegetables and carries their flavour into the sauce.
- Egg yolks
- Beaten yolks brushed over the eels, helping the coating set and brown.
- Bread crumbs
- Coating that forms a crisp, golden crust when broiled or baked.
- White wine
- Adds acidity and aroma to the sauce as it cooks down.
The step that matters
Browning the coated eels. The bread crumbs and egg yolks need enough heat to turn golden without drying the fish. Low, steady heat lets the crust brown while the eels stay moist, so watch them closely under the broiler or in the oven.

Fit is the average pairing score against butter, carrot, parsley, white wine, pepper, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
