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 ↓
Eel Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the eels
Skin, wash, and trim the eels, cutting them into 3-inch pieces.
Season the eels with pepper and salt, and place them in a dish, omitting the heads and tails.
Add ½ cup of water or veal broth.
Make the sauce
The sauce is made by boiling the trimmings in veal stock.
Season the sauce with pepper, salt, and lemon juice.
Thicken the sauce with flour and water.
Assemble and bake
Cover with puff pastry, brush with egg yolk, and decorate with pastry scraps.
Bake at 400°F (200°C) for 1 hour.
Make a hole in the center of the pie.
Pour the sauce into the hole.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main filling, which becomes tender and flavorful as it cooks in the pie.
- Puff pastry
- Forms a flaky, crisp crust that encloses the filling and browns in the oven.
- Egg yolk
- Brushed on the pastry to promote even browning and a glossy finish.
- Veal stock
- Builds the savory body of the sauce, adding depth from the boiled eel trimmings.
- Flour
- Thickens the sauce so it holds together rather than running out of the pie.
- Lemon juice
- Adds acidity that brightens the rich eel and sauce flavors.
The step that matters
Thicken the sauce with flour and water. Flour must be mixed smoothly with water before it is stirred into hot liquid, otherwise it clumps. Thickening then gives the sauce body so it stays in the pie when poured in.
