Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Stewed Eels
Ingredients
Directions
Prepare
Skin and clean the eels, then cut them into two-inch fillets.
Make the stew
In a stew-pan, melt the butter and sauté the sliced onion for 5 minutes.
Add the claret, fish 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.
Finish and serve
Arrange the eel on a serving dish, strain the gravy, thicken it, and reheat almost to boiling.
Add sugar and 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
- Conger eel
- Provides the main protein, which firms and flakes as it simmers in the gravy.
- Butter
- Adds richness and carries the flavour of the sautéed onion into the stew.
- Sliced onion
- Softens and sweetens as it sautés, building a savoury base for the gravy.
- Claret
- Adds acidity and wine flavour, helping to lift and deepen the gravy.
- Fish stock
- Supplies the liquid base of the gravy and reinforces the seafood flavour.
- Carrot
- Adds subtle sweetness and body to the gravy as it simmers.
The step that matters
Simmer the eel gently. Boiling vigorously can break up the fish and toughen its proteins, so keeping the gravy at a gentle simmer keeps the pieces intact and tender.
Swap the clove
How well each one fits the dish's main ingredients (freshwater eel, butter, onion, fish, garlic, carrot, pepper):

Fit is the average pairing score against freshwater eel, butter, onion, fish, garlic, carrot, pepper. Candidates are from the same food group and used in at least 100 recipes.
