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 ↓

What each ingredient does
- Salt mackerel
- Provides the main flesh and is salted, so soaking removes excess salt before cooking.
- Butter
- Adds richness and moisture to the cooked fish on the upper side.
The step that matters
Soaking the fish. Salt mackerel must soak long enough to draw out excess salt. Too little soaking leaves the fish harshly salty, while the gentle boil keeps the flesh tender rather than tough.
