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 ↓

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
Pound all the ingredients together.
Bake and serve
Spread the mixture on slices of toast.
Place in a 400°F (200°C) oven and bake for ten minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Melts and browns on top, providing richness and savory flavor.
- Egg yolks
- Bind the mixture and add richness and moisture to the spread.
- Bread crumbs
- Add body and help thicken the spread so it holds on the toast.
- Butter
- Adds fat for smooth texture and helps the topping brown in the oven.
- Mustard
- Adds sharp, tangy flavor that balances the richness of the cheese.
The step that matters
Bake until the topping is just set and golden. Egg yolks set when heated, so overbaking can make the topping dry or rubbery, while underbaking leaves it runny. Watching the color and firmness helps the cheese melt evenly and brown without scorching.
