Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Stuffed Conger Eel
Ingredients
Directions
The book says “a cool oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the eel
Prepare the veal seasoning as per another recipe.
Sew the seasoning into the eel.
Place the eel in a deep dish and cover it with water.
Bake in a 350°F (175°C) oven for about one hour.
Remove the eel and keep it warm.
Strain the cooking liquid.
Measure out 1 pint of the strained liquid and set aside.
Make the sauce
In a saucepan, melt the butter.
Whisk in the flour to make a roux.
Add the reserved cooking liquid to the roux, stirring until smooth.
Add caramel.
Bring the sauce to a boil.
Season with salt, pepper, and lemon juice.
Serve
Pour the sauce over the eel and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Conger eel
- Forms the main body of the dish and provides the flesh that is baked and served.
- Flour
- Thickens the cooking liquid into a sauce when cooked with butter as a roux.
- Butter
- Melts with the flour to form the roux that gives the sauce body and richness.
- Veal seasoning
- Stuffed into the eel, flavouring the fish from within as it bakes.
The step that matters
Make the roux before adding the liquid. Cooking the butter and flour together first cooks out the raw starch taste and lets the flour thicken smoothly. Adding liquid too quickly can leave lumps, so stir steadily while combining.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
