Why it works: Lemon and pepper 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 ↓

Ingredients
Directions
The book says “a slow oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the eels
Remove the heads and tails from the eels.
Stew the pieces in meat stock until cooked.
Strain out the heads and tails.
Make the sauce
Mix in pepper, salt, lemon juice, and mushroom ketchup.
Assemble and bake
Place the eel pieces in a pie dish.
Pour the sauce over them.
Cover with pie crust.
Bake at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Provide the main protein and body of the dish, with their flesh becoming tender when stewed.
- Meat stock
- Cooks the eels and forms the liquid base of the sauce, adding savoury depth.
- Lemon juice
- Adds acidity that brightens the rich flavour of the sauce.
- Mushroom ketchup
- Adds concentrated savoury, umami flavour to the sauce.
- Pie crust
- Encloses the dish and browns in the oven to form a golden top.
The step that matters
Bake until golden. Pie crust browns through Maillard reactions at oven heat, so it needs enough time at 400°F to turn golden. Pale crust suggests underbaking and a sauce that has not heated through.
Swap the lemon
How well each one fits the dish's main ingredients (meat, mushroom, ketchup, pepper):
- Lemonthe original
- Limefits about as well
- Red currantfits less well
- Avocadofits less well
Fit is the average pairing score against meat, mushroom, ketchup, pepper. Candidates are from the same food group and used in at least 100 recipes.
