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. Do not cut off the head.
Skin the eels by cutting around the neck and pulling the skin down with a cloth.
Gut the eels without breaking the gall, cut into 2-inch pieces, and soak in strong saltwater for 1 hour.
Dry the pieces, roll in seasoned flour, and fry in good dripping until lightly browned.
Drain the fried eels until cold to remove oily taste.
Stew and make the sauce
In a clean stew-pan, combine eels with bay leaf, onion with cloves, parsley, lemon rind, and stock.
Simmer gently for 20-30 minutes based on thickness.
Remove eels and keep warm while preparing the sauce.
Strain the gravy, thicken with flour, and add salt, cayenne, essence of anchovy, and lemon juice. Simmer for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Firm, oily flesh that holds its shape during frying and gentle stewing.
- Flour
- Seasoned flour coats the pieces, browning them and thickening the gravy.
- Good dripping
- Fat that fries the coated eel pieces, adding browning and rich flavour.
- Stock
- Liquid that gently cooks the eels and forms the base of the gravy.
- Essence of anchovy
- Adds a salty, savoury depth to the finished gravy.
- Lemon juice
- Adds acidity that brightens the rich, oily gravy.
The step that matters
Drain the fried eels until cold. Eels are oily, and letting the fried pieces drain and cool lets excess fat run off, so the stew does not taste greasy.
Swap the onion
How well each one fits the dish's main ingredients (flour, pepper, clove, parsley, lemon, anchovy):
