Souffle Au Parmesan

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. Combine the butter, water, pepper, salt, and sugar in a small saucepan.

  2. Bring the mixture to a boil and remove from heat.

  3. Stir in the flour vigorously over low heat until the mixture detaches from the sides of the saucepan.

  4. Transfer the mixture to a bowl.

  5. Let it cool slightly while stirring with a wooden spoon.

Finish and bake

  1. Mix in the egg yolks, grated Parmesan, and small pieces of butter gradually, stirring continuously.

  2. Fold in the whipped egg whites gently.

  3. Pour the mixture into a well-buttered tin.

  4. Place the tin on a wire rack in a 350°F (175°C) oven.

  5. Bake for 25 minutes or until the souffle is puffed and golden.

What each ingredient does

Eggs yolks
Add richness and emulsify the base, giving a tender, custard-like crumb.
Egg whites
Whipped and folded in, they trap air that lifts and gives the soufflé its rise.
Flour
Cooked with the butter and water into a paste that gives the soufflé structure.
Parmesan
Adds savoury flavour and fat, and helps the top brown as it bakes.
Butter
Adds fat and flavour, and enriches the texture of the base.

The step that matters

Folding in the whipped egg whites. Folding gently keeps the air bubbles in the whites intact. Stirring or deflating them makes the soufflé rise less and turn dense.
