Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Stewed Conger Eel with Curry Sauce
Ingredients
Directions
Prepare the fish
Remove the skin from the Conger Eel and cut it into fillets.
Soak the fillets in salted vinegar for 1 hour, then rinse and dry them.
Make the curry sauce
Chop the onion and brown it in butter.
Add the fish pieces to the pan and toss for a few minutes.
Season with salt and pepper, then sprinkle with flour and curry powder, cooking for a few more minutes.
Add enough water and white wine to cover the fish, along with spices and parsley, and bring to a boil.
Reduce heat and let it simmer gently until the fish is cooked through.
Remove the parsley, take out the fish, and thicken the sauce with the egg yolks.
Strain the sauce over the fish and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Conger eel
- Provides the firm, mild white flesh that is the main component of the dish.
- Onion
- Browned in butter to add savoury sweetness and depth to the sauce.
- Flour
- Thickens the cooking liquid together with the curry powder's fat, giving the sauce body.
- Curry powder
- Adds warm spice aroma and flavour to the sauce.
- Egg yolks
- Enrich and thicken the finished sauce as they set gently with heat.
- White wine
- Adds acidity and aroma to the cooking liquid.
The step that matters
Thickening the sauce with egg yolks. Egg yolks thicken when gently heated but can scramble and curdle if the sauce boils. Keep the sauce below a simmer and stir while adding them, then strain for a smooth result.
