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 ↓
Scalloped Tomatoes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Drain most of the juice from the can of tomatoes and set the juice aside for another use.
Layer and bake
In a buttered dish, layer bread crumbs on the bottom.
Add a layer of tomatoes seasoned with salt, pepper, bits of butter, onion slices, and a little sugar.
Repeat with another layer of crumbs and another layer of seasoned tomatoes.
Top with a final layer of fine dry crumbs.
Bake covered at 400°F (200°C) until bubbling hot and brown.

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 acidic, juicy filling that softens during baking.
- Bread crumbs
- Absorb tomato liquid and form soft layers that hold the dish together.
- Butter
- Adds richness and helps the top and edges brown in the oven.
- Onion
- Adds savory aroma and flavor that mellows as it bakes with the tomatoes.
The step that matters
Drain most of the juice from the can. Excess liquid would make the layers soggy and watery, so draining keeps the crumbs from turning to mush and lets the top brown.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, butter, sugar, bread):
- Capsicumfits better
- Potatofits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, butter, sugar, bread. Candidates are from the same food group and used in at least 100 recipes.
