Why it works: Butter and bread 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 ↓
Cheese Omelet
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Butter the sides of a deep dish.
Cover the bottom with thin slices of cheese.
Layer very thin slices of buttered bread on top.
Sprinkle with a little red pepper and mustard.
Add another layer of cheese.
Bake and serve
Beat the egg yolk in a cup of cream and pour into the dish just before baking.
Bake at 350°F (175°C) for 30 minutes or until nicely browned.
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
- Eggs
- Egg yolk beaten into cream sets during baking to give the dish a custard-like body.
- Cream
- Adds moisture and richness, so the layers bake into a tender, custardy texture.
- Thin slices of cheese
- Melts between the bread layers and browns on top, adding richness and savory flavor.
- Thin slices of bread
- Forms the layers that soak up the cream mixture and hold the dish together.
The step that matters
Pour the egg and cream mixture just before baking. Egg proteins set with heat, and standing too long lets the bread soak unevenly and the custard lose its loose, even texture before the oven.
Swap the mustard
How well each one fits the dish's main ingredients (butter, cheese, bread, pepper, egg, cream):
- Potatofits better
- Asparagusfits better
- Capsicumfits better
- Mustardthe original
Fit is the average pairing score against butter, cheese, bread, pepper, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
