A Fondu, or Cheese 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the base

  1. Preheat the oven to 350°F (175°C).

  2. Melt butter in a saucepan, add flour, and stir until smooth.

  3. Gradually add milk, stirring until thickened.

  4. Remove from heat and mix in cheese, salt, and pepper.

Bake and serve

  1. Beat the eggs and fold them into the cheese mixture.

  2. Pour into a greased baking dish and bake for 30-40 minutes until puffed and golden.

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

What each ingredient does

Eggs
Beaten eggs trap air and expand in the oven, giving the soufflé its lift and light texture.
Flour
Flour thickens the melted butter and milk into a smooth sauce that holds the soufflé together.
Cheese
Cheese adds rich flavor and fat, and helps set the custard as it cooks.
Milk
Milk forms the liquid base of the white sauce, adding moisture and body.
Butter
Butter enriches the base and, with flour, forms the roux that thickens the sauce.

The step that matters

Fold the eggs into the cheese mixture. Folding gently keeps the air in the beaten eggs. Stirring or deflating the mixture loses the bubbles that make the soufflé rise.
