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 Fondu
Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
In a saucepan, melt the butter and stir in the flour over medium heat.
Add the grated cheese and stir for 20 minutes, then remove from heat and let cool.
Beat the egg yolks and add them to the cooled mixture.
Bake and serve
Beat the egg whites until stiff and fold them into the mixture just before baking.
Pour the mixture into a silver fondue dish or a round cake tin lined with frilled paper.
Bake at 400°F (200°C) for about 45 minutes.
Serve hot, as it will fall while cooling.

Butter and flour 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
- Whipped whites trap air for lift, and yolks add richness and help set the custard.
- Butter
- Fat that carries flavor and gives the base a rich, tender texture.
- Flour
- Thickens the melted butter into a roux that gives the mixture body and structure.
- Grated cheese
- Adds the main flavor and fat, and helps the mixture set as it bakes.
- Milk
- Adds moisture and loosens the base so it bakes into a soft, custardy texture.
The step that matters
Fold the egg whites in just before baking. Whipped whites hold the air that makes the fondue rise. If they are folded in too early or overmixed, they deflate and the fondue loses its lift and softness.
“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.
