Why it works: Pepper and butter are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 85,593 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Cold Storage Kippers
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Pour cold water over the kippers.
Place the kippers in a fireproof dish while still wet.
Sprinkle the kippers with pepper.
Add small dabs of butter to the kippers.
Cover the dish.
Cook and serve
Cook in a slow oven at 300°F (150°C) for about five minutes.
Serve in the same dish.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Kippers
- Provide the main fish, which cooks gently in steam under the cover.
- Cold water
- Wets the kippers so they steam rather than dry out in the oven.
- Butter
- Adds fat and richness, carrying flavour and keeping the fish moist.
The step that matters
Cover the dish. The lid traps steam around the wet kippers, gently heating them through and keeping the flesh moist. Leaving the dish uncovered lets moisture escape, so the fish can dry out and toughen in the slow oven.
