Custard Souffle

Oven, in the book's wordsA moderate oven

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

  1. Cream the butter in a bowl.

  2. Add the cornstarch and gradually pour in the hot milk, stirring constantly.

  3. Cook in a double boiler for 10 minutes, stirring often.

  4. Separate the egg whites and yolks; place the whites in a cool place.

  5. Beat the yolks and mix in the sugar.

  6. Once the milk mixture has slightly cooled, stir in the yolk mixture.

Bake and serve

  1. Beat the egg whites until stiff and gently fold them into the mixture.

  2. Pour into a buttered pudding dish and bake at 350°F (175°C) for about 30 minutes.

  3. Serve immediately with a creamy sauce.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg whites
Whipped to stiff peaks, they trap air and give the souffle its light, risen structure.
Egg yolks
Enrich the custard and help it set, adding richness and a smooth texture.
Cornstarch
Thickens the hot milk into a custard base that can support the folded whites.
Hot milk
Forms the liquid base of the custard, adding moisture and a soft texture.
Sugar
Adds sweetness and balances the richness of the yolks and butter.

The step that matters

Fold in the egg whites gently. Whites hold air only when whipped to stiff peaks and folded gently. Overmixing knocks out the air, so the souffle will not rise well in the oven.
