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 ↓
Cheese 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
In a small saucepan, melt the butter and flour over medium heat until bubbling.
Add the milk or cream and stir to prevent burning until smooth.
Stir in the grated cheese, salt, and cayenne until well mixed.
Remove from heat and stir in the beaten egg yolks.
Bake and serve
Whisk the egg whites until stiff and gently fold them into the mixture.
Butter a baking dish that will be half filled with the mixture.
Bake in a preheated oven at 400°F (200°C) until golden brown.
Wrap a napkin around the dish and serve immediately to prevent it from falling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whisked until stiff, they trap air that lifts the mixture as it bakes.
- Egg yolks
- Thicken the cheese base and add richness once stirred in off the heat.
- Cheese
- Provides the main flavor and melts into the sauce for a creamy body.
- Flour
- Cooked with butter to form a roux that thickens the milk or cream.
- Milk or cream
- Forms the liquid base that the roux thickens into a smooth sauce.
The step that matters
Folding in the egg whites. Stiff whites hold the air that makes the fondue rise. Overmixing or stirring them in vigorously deflates the foam, so the dish bakes flat and dense.
