Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Scalloped Salmon
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the bones and skin from the salmon and break it into pieces.
In a baking dish, layer the salmon with alternating layers of cracker crumbs.
Make the sauce
In a saucepan, melt the butter and stir in the flour until smooth.
Add the milk and cook until it boils.
Bake and serve
Pour the sauce over the salmon and cracker layers.
Bake at 350°F (175°C) for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body of the dish and provides its flavor and flaky texture.
- Cracker crumbs
- Soak up the sauce and give the layers a soft, bound texture.
- Butter
- Adds richness and fat, and helps the flour blend smoothly into the sauce.
- Flour
- Thickens the milk into a smooth sauce that binds the layers together.
- Milk
- Forms the liquid base of the sauce, adding moisture and creaminess.
The step that matters
Bring the sauce to a boil. Flour thickens milk only once its starch granules have swollen in hot liquid, so the sauce must reach a full boil to set properly. Stirring while adding the milk keeps the flour from forming lumps.
