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 the juice from the can of tomatoes and set aside for soup.
In a buttered pie dish, layer bread crumbs.
Layer and bake
Add a layer of tomatoes, seasoning with salt, pepper, and small bits of butter, plus a little sugar.
Repeat with another layer of crumbs and tomatoes.
Finish with a top layer of fine, dry crumbs.
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 acidic, juicy filling that softens and bubbles while baking.
- Bread crumbs
- Absorb tomato liquid and form a soft layered structure, then crisp and brown on top.
- Butter
- Adds richness and fat that carries flavor and helps the top brown.
- Sugar
- Adds a little sweetness to balance the acidity of the tomatoes.
The step that matters
Uncovering to brown. Baking covered traps steam so the tomatoes heat through without drying. Uncovering at the end lets surface moisture evaporate, allowing the crumbs to brown quickly rather than stay pale and soggy.
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.
