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 ↓
Baked Mackarel
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Lay the mackerel in a baking pan.
Season the fish with coarse sea salt, black pepper, and spices.
Bake and serve
Add a few bay leaves and a little butter on top.
Cover the pan tightly with strong paper.
Bake in the oven until cooked through.
Serve with plain butter and soy sauce or ketchup.

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
- Mackerel (in the method)
- The main fish, which becomes flaky and tender as its proteins set with heat.
- Butter
- Adds fat and richness, helping the fish stay moist and carrying flavour as it melts.
- Bay leaves
- Release aromatic oils into the fish as it bakes, adding a subtle herbal scent.
The step that matters
Cover the pan tightly and bake until cooked through. Covering traps steam, so the fish cooks gently and stays moist. Baking until it is fully cooked matters for safety, while overbaking dries out the flesh and makes it tough.
