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 ↓
Fish Souffle
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.
Make the sauce base
In a saucepan, melt the butter over medium heat.
Stir in the flour, salt, and cayenne pepper, cooking for 1-2 minutes.
Gradually add the milk, stirring constantly until the mixture thickens.
Remove from heat and let it cool slightly.
Build the soufflé
Beat the egg yolks and mix them with the flaked fish into the sauce.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the egg whites into the fish mixture.
Pour the mixture into a buttered baking dish.
Bake and serve
Bake in a 350°F (175°C) oven or steam over gently boiling water for 30-35 minutes, or 20 minutes for small molds.
Serve immediately with Drawn Butter or Tomato Sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites whipped to stiff peaks trap air, lifting the soufflé as it bakes, while yolks enrich the set custard.
- Flour
- Cooked with butter and milk, it thickens the base into a sauce that holds the fish and air.
- Butter
- Enriches the roux and adds flavour and tenderness to the sauce base.
- Milk
- Forms the liquid of the thickened sauce, giving the soufflé its moist, creamy body.
- Cooked fish
- Provides the main flavour and body of the soufflé mixture.
The step that matters
Folding in the egg whites. Whites are whipped to stiff peaks to hold air. Folding gently keeps that air in; stirring hard deflates the foam, so the soufflé rises less and turns dense.
