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 Fondu
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.
Prepare
In a baking dish, mix the grated cheese, bread crumbs, salt, pepper, mustard, and cayenne pepper.
Beat the egg in a separate bowl, then add the milk and mix well.
Pour the egg and milk mixture over the dry ingredients.
Melt the butter and add it to the mixture.
Bake
Bake in a 400°F (200°C) oven for 15 to 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grated cheese
- Provides the main flavor and melts into a rich, gooey body when baked.
- Stale bread crumbs
- Absorb the milk and egg mixture, giving the dish structure and body as it bakes.
- Egg
- Binds the mixture and helps it set into a firm, sliceable texture.
- Milk
- Adds moisture and softens the bread crumbs so the mixture bakes creamy.
- Butter
- Adds fat for richness and smoother texture.
The step that matters
Pour the egg and milk mixture over the dry ingredients. Pouring the liquid over the dry mix without stirring lets the bread crumbs absorb it evenly; overmixing or uneven soaking can leave dry pockets or a dense, rubbery texture after baking.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, bread, milk, egg, butter, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against cheese, bread, milk, egg, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
