Why it works: Bread and butter 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide moisture and acidity that flavour the layers as they soften.
- Eggs
- Bind the layers together and set into a custard as they bake.
- Bread
- Soaks up juices and gives the layers body and structure.
- Cold meat
- Adds savoury flavour and substance to the layers.
- Butter
- Adds richness and helps the top and bread brown in the oven.
The step that matters
Pour the beaten eggs over the top and bake until browned. The eggs must set into a custard without overbaking, which would make them dry and rubbery. Browning on top is the visual cue that the layers are cooked through.

Fit is the average pairing score against meat, bread, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
