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 ↓
Fondue
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.
Make the base
In a saucepan, mix milk and flour to create a smooth paste.
Add grated cheese, salt, mustard powder, and pepper; mix well.
Beat the egg yolks with milk, then strain and add to the mixture.
Bake and serve
Incorporate the beaten egg whites until frothy.
Pour the mixture into a deep round tin.
Bake at 350°F (175°C) for 20 to 30 minutes until golden brown.
Serve immediately in the tin with a napkin around it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help bind the custard-like base as it sets.
- Egg whites
- Whipped into the mixture to trap air, lightening the texture and helping it rise.
- Flour
- Thickens the milk into a smooth paste that gives the fondue its body.
- Grated cheese
- Provides the main flavour and, as it melts, adds richness and savouriness.
- Milk
- Forms the liquid base that the flour thickens and the eggs enrich.
The step that matters
Incorporate the beaten egg whites until frothy. Egg whites must be beaten to hold air; if they are overmixed or deflated, the mixture loses its lift and bakes up dense.
Swap the mustard

Fit is the average pairing score against egg, milk, flour, cheese, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
