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 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 custard base
Cream the butter in a bowl.
Beat in the flour, then gradually pour in the boiling hot milk.
Cook in a double boiler for about 5 minutes, stirring often.
Beat the egg yolks until thick, add the sugar, and stir into the cooking mixture.
Remove from heat and let cool.
Bake and serve
About 30 minutes before serving, fold in the stiffly beaten egg whites.
Bake in a buttered pudding dish at 350°F (175°C) for about 30 minutes.
Serve immediately with a creamy sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard base, and whites are beaten to add lift to the soufflé.
- Flour
- Starch thickens the milk mixture into a stable base that holds the soufflé together.
- Milk
- Forms the liquid base of the custard, adding moisture and richness.
- Butter
- Adds fat for richness and flavor in the starting base.
- Sugar
- Adds sweetness and balances the flavor of the custard base.
The step that matters
Folding in the egg whites. Stiffly beaten whites trap air that makes the soufflé rise. Folding gently keeps that air in; stirring or deflating the batter leaves a dense, flat result.
