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
Beat the yolk of an egg in a cup of cream and pour into the dish.
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 binds the cream into a custard that sets around the bread and cheese.
- Cream
- Adds moisture and richness, so the custard stays soft and tender as it bakes.
- Cheese
- Melts into the layers and adds savory flavor and richness.
- Thin slices of bread
- Soaks up the custard and gives the bake a soft, layered structure.
- Butter
- Adds fat and flavor, and helps the bread brown on its surface.
The step that matters
Bake until nicely browned. The custard sets as egg proteins firm with heat. Baking too briefly leaves it runny, while overbaking can make it rubbery and dry.
Swap the mustard

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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
