Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Stewed Eels a LA Francaise
Ingredients
Directions
Prepare
Clean, skin, and cut the eels into 2-inch pieces.
In a saucepan, combine eels, parsley, thyme, onion, butter, lemon juice, pepper, salt, and enough boiling water to cover.
Cook gently until tender.
Make the sauce
Remove eels with a perforated spoon and keep warm.
Strain the gravy, thicken with flour, and boil for 3 minutes.
Beat 2 eggs, stir into the sauce quickly, and remove from heat before curdling.
Pour sauce over the eels and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main body of the dish, becoming tender during gentle cooking.
- Flour (in the method)
- Thickens the strained gravy so it coats the eels.
- Eggs (in the method)
- Enrich and thicken the sauce as they set with gentle heat.
- Butter
- Adds richness and a silky mouthfeel to the gravy.
The step that matters
Adding the beaten eggs to the sauce. Egg proteins set with heat and can curdle if the sauce is too hot or stirred too slowly. Stirring quickly and removing the pan from heat before it curdles keeps the sauce smooth and thickened.
Swap the onion
How well each one fits the dish's main ingredients (parsley, thyme, butter, lemon, pepper):
- Shallotfits better

- Onionthe original
Fit is the average pairing score against parsley, thyme, butter, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
