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 ↓
Custard Souffle'
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard base
Heat the milk in a saucepan until it boils.
Beat together the flour and butter in a bowl.
Gradually add the boiling milk to the flour and butter mixture, cooking for 8 minutes while stirring often.
Beat the sugar and egg yolks together in another bowl.
Combine the cooked mixture with the egg yolk mixture.
Let the mixture cool.
Fold and bake
Beat the egg whites until stiff.
Fold the stiff egg whites into the mixture.
Pour the mixture into a buttered pudding dish.
Bake for 20 minutes at 350°F (175°C).
Serve
Serve immediately with creamy 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 provide the airy structure that lifts the soufflé, while yolks enrich and set the custard.
- Flour
- Thickens the milk into a stable white sauce that holds the soufflé base together.
- Butter
- Enriches the base with fat, adding richness and a tender texture.
- Milk
- Forms the liquid base of the custard, which is thickened by the cooked flour.
- Sugar
- Adds sweetness and balances the flavor of the custard base.
The step that matters
Fold the stiff egg whites into the mixture. Folding gently preserves the air trapped in the whipped whites. Stirring or deflating them makes the soufflé rise poorly and turn dense.
