Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the herring
Flake the salted herrings, removing bones and skin.
Layer the herring in a tin baking dish.
Layer the dish
Add peppercorns and sprinkle chopped onion over the herring.
Add a layer of bread crumbs.
Repeat layers until the dish is full, finishing with bread crumbs and bits of butter or dripping.
Bake and serve
Bake in a moderate oven at 350°F (175°C) until golden.
Drizzle with lemon juice before serving, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salted herrings
- Provide the main fish flavour and the body of the dish.
- Bread crumbs
- Form layers that soak up juices and brown to a golden crust.
- Butter or good dripping
- Adds fat for richness and helps the top crust turn golden.
- Finely chopped onion
- Adds savoury sweetness and aroma as it cooks.
The step that matters
Finishing with bread crumbs and fat. Crumbs and bits of butter or dripping on top need to cover the surface evenly, because the fat is what browns the crust in the oven and keeps the top from drying out.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (onion, bread, butter):
- Avocadofits better
- Coconutfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against onion, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
