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 ↓
Toasted Cheese
Ingredients
Directions
Make the topping
In a saucepan, mix the cheese, bread crumbs, butter, egg yolks, cream, mustard, salt, and pepper.
Stir over medium heat until heated through.
Assemble and brown
Spread the mixture thickly on toasted bread.
Brown it under a broiler or in a Dutch oven until the cheese is just brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Melts and browns to give the topping its rich, savoury flavour and body.
- Bread crumbs
- Add bulk and body so the mixture spreads thickly rather than running.
- Butter
- Adds fat for richness and helps the mixture stay smooth when heated.
- Egg yolks
- Thicken the mixture as they heat, binding it into a spreadable custard-like paste.
The step that matters
Brown it until the cheese is just brown. Egg yolks and cheese can turn grainy or tough if overheated, so brown gently and watch closely once the cheese begins to colour.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, bread, butter, egg, cream, pepper):
- Potatofits better
- Asparagusfits better
- Capsicumfits better
- Mustardthe original
Fit is the average pairing score against cheese, bread, butter, egg, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
