Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Hot Cheese Souffle or Fondue
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Melt the butter in a saucepan.
Add the flour and mix to a smooth paste.
Stir in the milk and cook over medium heat until it boils.
Cook thoroughly, then remove from heat.
Make the soufflé
Beat the egg whites until stiff peaks form.
Add the beaten yolks to the mixture when slightly cool.
Stir in the cheese, salt, pepper, and cayenne.
Fold in the egg whites gently.
Pour the mixture into a prepared baking dish.
Bake and serve
Bake at 400°F (200°C) for 20 minutes or until firm on top.
Serve immediately, as it will fall quickly.

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 enrich the base and help set it.
- Butter
- Fat that enriches the base and carries flavour into the roux.
- Flour
- Forms a roux with the butter that thickens the milk into a stable base.
- Milk
- Liquid that the flour thickens into a smooth sauce base for the soufflé.
- Parmesan cheese
- Adds savoury, salty flavour and richness to the base.
The step that matters
Fold in the egg whites gently. Whites hold air only when their foam is stiff and unbroken. Overmixing deflates the foam, and the soufflé then rises poorly and falls quickly in the oven.
“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.
