Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Stewed Eels
Ingredients
Directions
Prepare the eels
To kill the eels, insert a skewer into the spinal marrow behind the head without cutting it off.
Skin the eels by cutting around the neck and pulling the skin down with a cloth.
Gut the eels carefully, avoiding the gall, and cut into 2‑inch pieces.
Soak the pieces in strong saltwater for 1 hour.
Dry the pieces, roll them in seasoned flour, and fry in dripping until lightly browned.
Drain the fried eels until cool to remove excess oil.
Stew and make the sauce
In a clean stew‑pan, combine the eels with bay leaf, onion, parsley, lemon rind, and stock.
Simmer gently for 20–30 minutes, depending on thickness.
Remove the eels and keep them warm.
Strain the gravy, thicken with flour, and season with salt, cayenne, essence of anchovy, and lemon juice.
Simmer the sauce for 10 minutes, adding red wine if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Main protein; firm, oily flesh that holds its shape during frying and stewing.
- Flour
- Coats the eels for browning and later thickens the gravy.
- Dripping
- Fat for frying, giving the coated eels a golden, savoury crust.
- Stock
- Liquid base that gently cooks the eels and forms the gravy.
- Lemon juice
- Adds acidity that brightens the rich, fatty gravy.
- Essence of anchovy
- Adds savoury depth to the sauce.
The step that matters
Simmer gently after frying. Vigorous boiling breaks up the delicate eel pieces and makes the gravy cloudy, so keep the stew at a low simmer.
Swap the onion
