Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Cheese Fondue

Add the milk, bread crumbs, grated cheese, salt, red pepper, and mustard. Mix well.
Place the pot over boiling water and heat until hot.
Stir in the beaten eggs and cook, stirring constantly, until thickened (about 3 minutes).
Serve

Optionally, add a little Worcestershire sauce for extra flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the cheese mixture as they cook, giving the fondue a creamy, set body.
- Grated cheese
- Provides the main flavor and melts into the sauce to give it richness and body.
- Milk
- Forms the liquid base that the cheese melts into, keeping the fondue smooth and pourable.
- Bread crumbs
- Absorb liquid and help thicken the mixture, adding body to the sauce.
The step that matters
Stir in the beaten eggs and cook, stirring constantly, until thickened. Egg proteins set when heated, so constant stirring over gentle heat keeps the mixture smooth. Overheating or leaving it still can curdle the eggs and make the fondue grainy.
Swap the mustard
How well each one fits the dish's main ingredients (butter, milk, bread, cheese, pepper, egg):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against butter, milk, bread, cheese, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
