Why it works: Cheese and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,130 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Cheese Sandwiches
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Make the cheese filling
Scald the milk and remove it from the heat.
Add the egg yolk, cheese, egg white, and seasonings to the milk.
Bring the mixture to a boil, then remove it from the heat.
Allow the mixture to cool, then spread it between slices of buttered bread.
Cut and toast
Cut the sandwiches thin.
Toast them in a hot oven (400°F / 200°C) in a pan, turning them over.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- New york cheese
- Melts into the filling and gives the sandwich its main flavor and richness.
- Egg
- Thickens the cheese mixture as it heats and helps it set when cooled.
- Sweet milk
- Melts the cheese smoothly and keeps the filling moist and creamy.
The step that matters
Bring the mixture to a boil, then remove it from the heat. Egg proteins thicken with heat, but overheating can curdle the egg and make the filling grainy. Stop once it boils and let it cool to thicken gently.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, egg, milk, pepper, bread):
- Capsicumfits better
- Tomatofits better
- Asparagusfits better
- Mustardthe original
Fit is the average pairing score against cheese, egg, milk, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
