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 ↓

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).
Assemble
In a baking dish, layer ½ cup of bread crumbs and season with salt, pepper, and a little butter.
Add a layer of tomatoes dredged with flour and seasoned.
Repeat layers until the dish is full, finishing with a layer of bread crumbs on top.
Dot the top with butter before baking.
Bake
Bake until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and moisture that softens and forms the sauce as they bake.
- Bread crumbs
- Form the layers and absorb tomato juices, giving a soft, browned, slightly crisp top.
- Butter
- Adds richness and helps the top brown evenly in the oven.
- Flour
- Dusted on the tomatoes, it helps thicken the juices into a looser sauce.
The step that matters
Bake until golden brown. Baking long enough lets the tomato juices thicken with the crumbs and the top brown. Pulling the dish too early leaves it watery, while over-baking dries it out.
Swap the tomato
How well each one fits the dish's main ingredients (bread, butter, flour, pepper):
- Shallotfits better
- Capsicumfits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against bread, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
