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 ↓
Vanilla 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.
Prepare
Preheat the oven to 350°F (175°C).
Separate the eggs, placing the yolks in one bowl and the whites in another.
Melt the butter and mix it with the flour and salt.
Add the milk and castor sugar to the butter mixture, stirring until smooth.
Make the soufflé
Whisk the egg whites until stiff peaks form.
Gently fold the egg yolks into the milk mixture, then fold in the egg whites.
Pour the mixture into a greased soufflé dish.
Bake and serve
Bake for 25-30 minutes until puffed and golden.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air that makes the soufflé rise, while yolks enrich the base and add richness.
- Butter
- Fat that combines with flour to form a roux, giving the base body and a rich flavour.
- Flour
- Thickens the butter and milk base so it can hold the whipped egg whites.
- Milk
- Liquid that turns the roux into a smooth, thick base for the soufflé.
The step that matters
Folding in the egg whites. Whites whipped to stiff peaks hold the air that lifts the soufflé. Stirring or overmixing them deflates the foam, so the soufflé rises less and turns dense.
