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 ↓
Scalloped Tomatoes
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 and layer
Skin the tomatoes and cut them into pieces.
Layer tomatoes in a baking dish with some shredded onion, seasoning with pepper and coarse sea salt.
Add a layer of bread crumbs and dot with plenty of butter.
Repeat with another layer of tomatoes and finish with a layer of bread crumbs.
Bake
Bake in a 350°F (175°C) oven until brown, then cover and steam for about 45 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 steams into the sauce as the dish bakes.
- Bread crumbs
- Absorb tomato juices and form a soft layer that browns on top.
- Butter
- Adds richness and helps the top crumbs brown in the oven.
- Onion
- Adds savory flavor that deepens as it cooks with the tomatoes.
The step that matters
Covering to steam after browning. Browning the top first sets color and flavor, while covering afterward traps steam so the tomatoes soften and the crumbs stay moist rather than drying out.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, bread, butter):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Onionthe original
Fit is the average pairing score against tomato, pepper, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
