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 ↓
Roasted Cheese
Ingredients
Directions
Prepare the topping
Preheat a Dutch oven.
Beat the egg yolks.
Add the grated cheese, bread crumbs, butter, mustard, pepper, and salt, then mix well.
Assemble and heat
Toast the slice of bread.
Cut it into square pieces.
Spread the cheese mixture thickly over the toasted bread pieces.
Cover with a tin cover and place in the Dutch oven until heated through.
Remove the cover to allow the cheese to brown slightly.
Serve
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rich cheese
- Melts into the topping and provides the main savory flavor and richness.
- Egg yolks
- Add richness and help bind the cheese mixture into a spreadable paste.
- Bread crumbs
- Add body to the mixture so it spreads thickly rather than running.
- Butter
- Adds fat that carries flavor and helps the topping soften and brown.
The step that matters
Covering, then uncovering to brown. Covering traps steam so the cheese heats through gently without drying out. Removing the cover lets surface moisture escape, so the cheese browns slightly; leaving it covered too long leaves it pale and soft.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, egg, bread, butter, pepper):

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