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 ↓
Salmon Au Gratin
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the salmon
Remove the bones and skin from the warm cooked salmon.
Break the fish into flakes or small pieces.
Season with pepper and a little cayenne pepper.
Assemble
Moisten with béchamel sauce and mix in some grated Parmesan cheese and bread crumbs.
Arrange the mixture neatly in a buttered gratin dish.
Sprinkle with more grated Parmesan cheese and fine bread crumbs.
Dot with small bits of butter on top.
Bake and serve
Bake at 400°F (200°C) until light brown and serve in the same 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 flavour.
- Béchamel sauce
- Adds moisture and a creamy texture that keeps the fish from drying out.
- Grated parmesan cheese
- Adds savoury flavour and helps the top brown when baked.
- Bread crumbs
- Creates a crisp, golden topping and absorbs excess moisture.
- Butter
- Adds richness and helps the topping brown in the oven.
The step that matters
Moisten with béchamel sauce. The sauce must be just enough to bind the flaked fish without making it wet or heavy. Too much liquid makes the gratin soggy and stops the topping from crisping in the oven.
