Why it works: Cheese and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 7,962 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Cheese Toast
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, mix the grated cheese, butter, and beaten egg white until well combined.
Bake and serve
Heap the mixture onto the slices of toast.
Place the toast in the oven and bake until brown.
Serve hot with tea or coffee.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- American cheese
- Melts into a rich, stretchy layer that gives the toast its main flavor and body.
- Butter
- Adds fat that helps the topping spread, soften, and brown evenly in the oven.
- Egg white
- Binds the cheese and butter together and helps the topping set as it heats.
The step that matters
Bake until brown. Cheese can go from golden to burnt quickly, and the browning comes from the Maillard reaction. Watch closely so the topping browns without scorching or drying out.
