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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rich english cheese
- Provides the main flavor and, when melted, the creamy, stretchy body of the topping.
- Fine bread crumbs
- Add bulk and absorb melted butter, giving the topping a firmer, spreadable texture.
- Butter
- Adds fat that keeps the topping moist and helps it brown evenly in the heat.
- Egg yolks
- Bind the mixture and add richness, helping it set smoothly when heated.
- Mustard
- Adds sharpness that balances the richness of the cheese and butter.
The step that matters
Heat in a Dutch oven until lightly browned. Cheese and egg yolks can turn greasy or rubbery if overheated, while too little heat leaves the topping pale and unset. Watching for a light golden color lets the cheese melt and brown without drying out.
Swap the white pepper
How well each one fits the dish's main ingredients (cheese, bread, butter, mustard, egg):
- Capersfits better
- Tarragonfits better
- Nutmegfits better
- White pepperthe original
Fit is the average pairing score against cheese, bread, butter, mustard, egg. Candidates are from the same food group and used in at least 100 recipes.
