Why it works: Salmon and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 4,481 recipes. Both carry 2,6-nonadienal, which smells cucumber, green. The science ↓
Salmon Au Gratin
Ingredients
Directions
The book says “a moderately hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Separate the salmon into large flakes.
Place the flakes in a fireproof baking dish.
Sprinkle with salt and pepper, then cover with sauce.
Top and bake
Add a thin layer of lightly browned breadcrumbs.
Dot with small pieces of butter on top.
Bake at 400°F (200°C) for 8 to 10 minutes.
Serve in the baking dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked salmon
- Forms the main body of the dish and provides its flaky texture.
- Fish sauce or white sauce
- Adds moisture and richness so the salmon does not dry out while baking.
- Brown breadcrumbs
- Form a crisp, golden top layer through browning in the oven.
- Butter
- Adds fat and richness and helps the breadcrumb topping brown.
The step that matters
Bake at 400°F (200°C) for 8 to 10 minutes. The dish is already cooked, so baking is mainly for heating through and browning the breadcrumbs. Too long can dry the salmon and sauce, while too short leaves the centre lukewarm and the topping pale.
