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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Butter a baking dish generously.
Layer and bake
Layer sliced tomatoes in the dish.
Add a layer of thinly sliced cold meat.
Add a layer of buttered bread.
Repeat layers until the dish is full, seasoning each layer with pepper and salt.
Pour beaten eggs over the top.
Bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beaten eggs
- Set when baked to bind the layers into a firm, sliceable custard.
- Bread
- Soaks up juices and egg, giving the hash body and a soft texture.
- Sliced tomatoes
- Add moisture and acidity that mingle with the bread and eggs.
- Cold meat
- Adds savoury, salty flavour to each layer.
- Butter
- Adds richness and helps the top brown golden.
The step that matters
Bake until golden brown. Egg proteins set as they heat, so stopping at golden brown keeps the custard tender. Overbaking squeezes out liquid and makes the eggs rubbery and dry.
Swap the tomato
