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 ↓
Eel Pie
Ingredients
Directions
The book says “a fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the stock
Clean and skin the eels, then cut them into 2-inch pieces.
In a stewpan, combine the heads, tails, and fins of the eels with the meat stock and simmer for about 30 minutes.
Strain and skim the stock well.
Add the lemon juice and mushroom ketchup to the stock, then pour half of it into the pie dish.
Assemble and bake
Place the eel pieces in a pie dish, seasoning with salt and pepper between the layers.
Cover with pastry and bake at 400°F (200°C) for about 1 hour.
Warm the remaining stock and pour it into the pie through a funnel as soon as it is taken from the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Form the main filling, providing the meat and rich flavour of the pie.
- Meat stock
- Provides the liquid base that becomes the savoury sauce in the pie.
- Puff pastry
- Forms the crisp, flaky crust that browns in the oven over the filling.
- Mushroom ketchup
- Adds deep savoury, umami flavour to the stock.
- Lemon juice
- Adds acidity that brightens the rich stock and balances its savoury flavour.
The step that matters
Pouring the stock through a funnel after baking. The stock is poured in hot, straight from the oven, so the pastry stays puffed and the filling stays moist. Cooled or added too early, the stock can soak the pastry and leave the filling dry or unevenly set.
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.
