Why it works: Milk and butter 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 ↓
Parmesan Fondue
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Mix the flour with a little cold water to form a smooth paste.
Stir in the boiling milk.
Season with pepper, salt, and mustard, then add the butter and Parmesan.
Set the mixture aside to cool.
Finish and bake
Grease a mold large enough to allow for rising.
Beat the egg yolks and stir them into the batter.
Whisk the egg whites to a solid froth and fold them in just before baking.
Bake in a 400°F (200°C) oven until set, then serve immediately.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites whipped to a froth lift and structure the mixture as it bakes and sets.
- Flour
- Forms a smooth paste with cold water that thickens the milk into a stable base.
- Parmesan cheese
- Adds savoury flavour and fat, and its proteins help the baked mixture set firmly.
- Butter
- Adds richness and fat, giving the base a smooth, silky texture.
- Milk
- Hydrates the flour paste and forms the creamy body of the base.
The step that matters
Folding in the egg whites. Whites must be whisked to a solid froth and folded in gently just before baking. Overmixing deflates the air bubbles, so the fondue rises less and sets less lightly.
Swap the mustard
