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 nearly all the juice from the can of tomatoes and set aside for soup.
Assemble
In a buttered pie dish, layer bread crumbs.
Add a layer of tomatoes, seasoning with salt, pepper, butter, and a little sugar.
Repeat with another layer of crumbs and tomatoes, then top with fine, dry crumbs.
Bake and serve
Bake covered at 400°F (200°C) until bubbling hot, then uncover to brown quickly.

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 acidity, with their juice mostly drained off to keep the dish moist but not soupy.
- Bread crumbs
- Absorb tomato liquid and form soft layers that set into a spoonable, scalloped texture.
- Butter
- Adds richness and helps the top brown when uncovered in the oven.
- Sugar
- Adds a touch of sweetness that balances the acidity of the tomatoes.
The step that matters
Uncovering to brown. Baking covered first heats the dish through without drying it. Uncovering at the end lets the surface brown quickly; leaving it covered would leave the top pale and soft.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, butter, sugar, bread):
- Capsicumfits better
- Potatofits about as well
- Sweet potatofits about as well
- Tomatothe original
Fit is the average pairing score against pepper, butter, sugar, bread. Candidates are from the same food group and used in at least 100 recipes.
