Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Souffle Au Parmesan
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
Combine the butter, water, pepper, salt, and sugar in a small saucepan.
Bring the mixture to a boil and remove from heat.
Stir in the flour vigorously over low heat until the mixture detaches from the sides of the saucepan.
Transfer the mixture to a bowl.
Let it cool slightly while stirring with a wooden spoon.
Finish and bake
Mix in the egg yolks, grated Parmesan, and small pieces of butter gradually, stirring continuously.
Fold in the whipped egg whites gently.
Pour the mixture into a well-buttered tin.
Place the tin on a wire rack in a 350°F (175°C) oven.
Bake for 25 minutes or until the souffle is puffed and golden.

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