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
Cut the eels into pieces between 2 and 3 inches long, then remove the heads and tails.
Stew the heads and tails in ½ pint of meat stock until thoroughly cooked.
Strain out the heads and tails.
Make the sauce
Mix the stock with pepper, salt, lemon juice, and mushroom ketchup.
Assemble and bake
Place the eel pieces in a pie dish and pour the sauce over them.
Cover with pie crust and 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 meat, which turns tender and flaky when cooked in the sauce.
- Meat stock
- Carries the flavour of the stewed heads and tails and forms the body of the sauce.
- Mushroom ketchup
- Adds deep savoury, umami flavour to the sauce.
- Lemon juice
- Adds acidity that brightens the rich, savoury sauce.
- Pie crust
- Encloses the filling and browns in the oven to form a golden top.
The step that matters
Stew the heads and tails until thoroughly cooked. Heads and tails hold collagen and bones that only release gelatin and flavour after long, thorough stewing. Undercooked scraps leave the stock thin and bitter, and straining needs to wait until they are fully done.
Swap the lemon
How well each one fits the dish's main ingredients (mushroom, ketchup, meat, pepper):
- Lemonthe original
- Limefits about as well
- Red currantfits less well
- Avocadofits less well
Fit is the average pairing score against mushroom, ketchup, meat, pepper. Candidates are from the same food group and used in at least 100 recipes.
