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 ↓
Baked Fish with Cheese Sauce
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Place the cleaned fish in a baking dish.
Make the cheese sauce
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the milk, stirring constantly until thickened.
Add the grated cheese, salt, and pepper, and stir until melted.
Bake and serve
Pour the cheese sauce over the fish.
Bake for 25-30 minutes until the fish is cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish and cooks through in the oven.
- Butter
- Fat that combines with flour to form the base of the sauce.
- Flour
- Thickens the butter and milk into a smooth sauce.
- Milk
- Liquid that swells the flour into a thickened, creamy sauce.
- Cheese
- Melts into the sauce, adding richness and savory flavor.
The step that matters
Gradually add the milk, stirring constantly until thickened. Adding milk slowly while stirring keeps the flour evenly dispersed, preventing lumps. Starch granules swell as the sauce heats, so constant stirring gives a smooth, thick sauce.
