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 ↓
Hot Cheese Sandwiches
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
Cut each slice of bread into a 2-inch square.
Remove a smaller square from the center, leaving a ½-inch thick border.
Fill the hollow with a piece of American cheese.
Sprinkle with salt and paprika.
Cover with the top piece of bread to form a box.
Brush the top with melted butter or beaten egg white.
Bake and serve
Bake in a hot oven at 400°F (200°C) until browned.
Serve very hot on hot plates.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Forms the box-shaped case that holds the filling and gives the sandwich its structure.
- American cheese
- Melts inside the bread to create a soft, rich, gooey filling.
- Butter or egg white
- Promotes browning and gives the top crust a glossy, golden finish.
The step that matters
Bake until browned. High oven heat browns the bread through the Maillard reaction while the cheese melts inside. The thin ½-inch walls can scorch before the filling softens, so watch the sandwiches closely.
