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 base

  1. Boil the milk in a saucepan.

  2. In a separate bowl, rub together the butter and flour.

  3. Add the butter and flour mixture to the boiling milk and stir until thick.

  4. Let the mixture cool.

Make the custard and bake

  1. Beat the egg yolks with the sugar until light.

  2. In another bowl, beat the egg whites until light.

  3. Combine the yolk mixture with the thickened milk mixture, then gently fold in the egg whites.

  4. Pour the mixture into a baking dish and bake at 350°F (175°C) for 20 minutes.

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

What each ingredient does

Eggs
Whipped whites trap air for lift, while yolks add richness and set the custard.
Flour
Thickens the milk into a stable base that holds the egg structure.
Milk
Forms the liquid base that the flour thickens and the eggs set into custard.
Butter
Adds fat for a tender texture and rich flavour in the base.
Sugar
Sweetens the custard and helps the beaten yolks become light and smooth.

The step that matters

Fold in the egg whites gently. Whipped egg whites hold the air that makes a soufflé rise. Stirring them vigorously knocks out that air, so the soufflé bakes flat and dense.
