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 ↓
Carp Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the carp and filling
Scrape scales, gut, and wash the carp clean.
Boil the eel until almost tender, then pick off the meat and mince it finely.
Mix minced eel with bread crumbs, herbs, lemon peel, pepper, salt, nutmeg, anchovy, oysters, and egg yolks, then roll the mixture with butter and fill the carp's belly.
Make the sauce
Boil eel bones with mace, whole pepper, onion, herbs, and anchovy until reduced to half a pint.
Strain the liquid, add white wine and butter mixed with flour, then boil again.
Bake and serve
Prepare a pie crust, cover the dish, and place the carp inside.
Pour the sauce into the pie, cover with the lid, and bake for 1 hour at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp
- Forms the main body of the pie, supplying the flaky, mild fish that the filling complements.
- Eggs
- Egg yolks bind the minced filling and help it hold together when cooked.
- Butter
- Adds richness and fat, keeping the filling moist and giving the sauce body when mixed with flour.
- Bread crumbs
- Absorb moisture from the filling, giving it a softer, more cohesive texture.
- White wine
- Adds acidity and flavour to the sauce, brightening the richer ingredients.
- Oysters
- Contribute a briny, savoury flavour to the filling.
The step that matters
Reducing the eel bone stock to half a pint. Boiling concentrates the flavour of the stock; if it is not reduced enough the sauce will taste thin, and if over-reduced it may become too salty or intense once the wine is added.
Swap the nutmeg
How well each one fits the dish's main ingredients (bread, lemon, pepper, anchovy, oyster, egg, butter):
- Parsleyfits better
- Capersfits about as well
- Thymefits about as well
- Nutmegthe original
Fit is the average pairing score against bread, lemon, pepper, anchovy, oyster, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
