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 ↓
Stewed Eels
Ingredients
Directions
Prepare
Skin and clean the eels, then cut them into 2‑inch fillets.
Make the gravy
In a stew‑pan, melt the butter and sauté the sliced onion for 5 minutes.
Add the claret, stock, garlic, carrot, and sweet herbs; boil for 10 minutes while stirring.
Stir in the salt, spiced pepper, lime rind, and add the eel pieces.
Simmer for 30 minutes.
Serve
Arrange the eel on a hot dish, strain the gravy, thicken it, and reheat to almost boiling.
Add a pinch of sugar and chopped parsley, then pour the gravy around the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- The main protein; they become tender and flaky as they simmer slowly in the gravy.
- Butter
- Adds richness and carries the flavour of the sautéed onion into the gravy.
- Claret
- Adds acidity and wine flavour, which helps build the body of the stewing liquid.
- Stock
- Provides savoury body and moisture to form the gravy.
- Bombay onion
- Adds sweetness and savoury depth when softened in butter before the liquid is added.
The step that matters
Simmer for 30 minutes. Eels are delicate and can break apart or turn tough if the heat is too high. A gentle simmer cooks the fish through while keeping the pieces intact and tender.
Swap the clove
How well each one fits the dish's main ingredients (butter, onion, garlic, carrot, pepper, lime, parsley):
