Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Cheese Souffle
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Beat the yolks of the eggs well and thin them with a little milk, then add the grated cheese.
Rub the flour into a paste with a little more milk.
Heat the remaining milk in a saucepan until it boils, then stir in the flour paste.
Stir until smooth and creamy, then add the cheese and yolk mixture.
Boil for about a minute until the cheese is fully melted, then remove from heat.
Bake and serve
Whip the egg whites to a stiff froth and gently fold them into the mixture.
Fill paper cases with the preparation and bake for 15 minutes at 400°F (200°C).
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the base and whites, whipped stiff, lift the soufflé as it bakes.
- Flour
- Forms a paste with milk that thickens the sauce base and gives it body.
- Milk
- Forms the liquid base of the sauce that the flour thickens.
- Parmesan cheese
- Adds rich savoury flavour and melts into the base for a creamy texture.
The step that matters
Folding in the egg whites. Whites whipped to a stiff froth trap air that makes the soufflé rise. Folding gently keeps that air in; stirring vigorously deflates the mixture and the soufflé will not rise well.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
