Custaed 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 base

  1. Cream the butter in a bowl.

  2. Gradually add the flour and then pour in the hot milk, stirring constantly.

  3. Cook in a double boiler for 8 minutes, stirring often.

  4. Beat the egg yolks and mix in the sugar, then add to the milk mixture and let cool.

Bake and serve

  1. Half an hour before serving, 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 30 minutes.

  3. 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
Whipped whites give the soufflé its light, airy structure, while yolks add richness and set the base.
Flour
Thickens the butter and milk into a smooth base that holds the soufflé's structure.
Butter
Adds richness and flavor to the base, helping it feel smooth on the palate.
Milk
Forms the liquid base that the flour thickens into a custard.
Sugar
Sweetens the custard base and adds a little browning during baking.

The step that matters

Folding in the egg whites. Whites hold air only when beaten until stiff, and folding gently preserves that air. Stirring or deflating the mixture makes the soufflé heavy and flat once baked.
