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

  1. Boil the milk in a saucepan.

  2. In another pan, heat the butter and flour together.

  3. Gradually add the boiling milk to the butter and flour mixture.

  4. Cook for 8 minutes, stirring often.

  5. Beat the sugar and egg yolks together, then add to the cooked mixture and let it cool.

Bake and serve

  1. Once cool, beat the egg whites until stiff and fold them into the custard.

  2. Pour the mixture into a buttered pudding dish and bake at 350°F (175°C).

  3. Serve immediately with cream sauce.

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

What each ingredient does

Eggs
Whipped whites and yolks provide the lift and structure that set the souffle as it bakes.
Flour
Cooked with butter, it thickens the milk into a stable custard base.
Butter
Cooked with flour to form a roux, adding richness and body to the base.
Milk
Forms the liquid base that the flour thickens into custard.
Sugar
Adds sweetness and helps stabilise the beaten egg yolks.

The step that matters

Fold the beaten egg whites into the cooled custard. Folding gently keeps the air in the stiff whites. Deflating the foam makes the souffle rise less and turn dense when it bakes.
