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 ↓

Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Butter the sides of a deep dish.
Layer and bake
Cover the bottom with thin slices of cheese.
Layer thin slices of buttered bread on top.
Sprinkle a little red pepper and mustard over the bread.
Add another layer of cheese.
Beat the egg yolk in the cream and pour it into the dish.
Bake for 30 minutes or until nicely browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Binds the cream and sets into a custard-like texture when baked.
- Cream
- Adds moisture and richness so the layers become tender rather than dry.
- Cheese
- Melts between the layers and adds fat and savoury flavour.
- Bread
- Soaks up the egg and cream mixture, giving the dish body.
The step that matters
Beat the egg yolk in the cream and pour it into the dish. The yolk and cream must be well combined so the custard sets evenly; poorly mixed egg can leave streaks or pockets of uncooked liquid after baking.
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.
