Why it works: Bread and butter 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
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Assemble
Layer bread crumbs in a pudding dish.
Cover with small pieces of American cheese and season with coarse sea salt, paprika, dry mustard, and lumps of butter.
Repeat layers until the dish is almost full.
Beat the eggs and add the milk, then pour over the top.
Bake and serve
Bake at 400°F (200°C) for about 30 minutes.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when baked, binding the layers into a custard-like body.
- Milk
- Adds liquid that cooks with the eggs into a soft, moist custard.
- American cheese
- Melts into the layers, giving the dish its creamy, savoury body.
- Bread crumbs
- Soak up the egg and milk mixture, giving the dish structure and body.
- Butter
- Adds richness and fat that carries flavour and helps browning on top.
The step that matters
Pour the egg and milk mixture over the top. The eggs must be fully beaten into the milk so they set evenly as a custard. Unbeaten egg can leave streaks or pockets of uncooked white, and pouring over the layers lets the liquid soak down through the crumbs before baking.
Swap the mustard
How well each one fits the dish's main ingredients (bread, cheese, butter, egg, milk):
- Potatofits better
- Asparagusfits better
- Capsicumfits better
- Mustardthe original
Fit is the average pairing score against bread, cheese, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
