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 ↓
Cheese Fondu
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the base
Melt the butter in a saucepan.
Add the flour and mustard, stirring until combined.
Gradually stir in the milk and remove from heat.
Mix in the grated cheese, salt, and pepper.
Add the beaten egg and stir until well combined.
Bake and serve
Pour the mixture into a greased pie dish.
Bake for 10 to 15 minutes, or until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Sets the mixture into a firm, sliceable custard when baked.
- Flour
- Thickens the melted butter and milk into a smooth, stable sauce.
- Cheese
- Provides rich flavour and fat, adding body to the sauce.
- Milk
- Forms the liquid base that the flour thickens and the egg sets.
- Butter
- Adds fat and richness, and carries the flour for a smooth roux.
The step that matters
Remove the milk mixture from heat before adding the egg. If the base is too hot when the beaten egg goes in, the egg can scramble into lumps instead of blending smoothly. Stirring steadily while adding the egg keeps the mixture even and creamy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, cheese, flour, milk, butter, pepper):
- Potatofits better
- Capsicumfits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against egg, cheese, flour, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
