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 ↓
Herrings, Pie of
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Scale and clean the herrings, then cut off their heads, fins, and tails.
Split the herrings open, remove the bones, and season the inner surface with salt and pepper.
Grease a pie dish with butter and line the edge with pie crust.
Assemble the pie
Spread a layer of minced apples and onions (½ inch thick) on the bottom of the dish.
Place the prepared herrings on top of the apple and onion layer.
Cover the herrings with another layer of the apple and onion mixture.
Sprinkle the surface with grated nutmeg and finely shredded lemon rind.
Dot the top with small pieces of butter, pour in a little water, and cover with a pie crust.
Bake
Bake in a 400°F (200°C) oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Form the main filling and provide the rich, oily flavour that the pie is built around.
- Apples
- Add moisture and gentle sweetness that balance the fish's richness and soften during baking.
- Onions
- Contribute savoury sweetness and aroma as they soften under the crust.
- Butter (for topping)
- Adds fat that enriches the filling and helps the top crust brown.
- Pie crust
- Encloses the filling, holding in steam and moisture while the pie bakes.
The step that matters
Dot the top with butter, add water, then cover with crust. Water and butter give moisture and fat under the lid; without them the filling can dry out or scorch before the crust sets and browns.
Swap the apple
How well each one fits the dish's main ingredients (roe, pepper, butter, onion, nutmeg, lemon):
- Limefits better

- Applethe original
Fit is the average pairing score against roe, pepper, butter, onion, nutmeg, lemon. Candidates are from the same food group and used in at least 100 recipes.
