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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Melt the butter in a pan.
Add the bread crumbs to the melted butter.
Assemble
Mix half of the buttered crumbs with the stewed tomatoes, grated onion, salt, and pepper.
Pour the mixture into a buttered baking dish and cover with the remaining crumbs.
Bake
Bake at 350°F (175°C) until brown, about 40 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stewed tomatoes
- Provide the main body, moisture and acidity of the dish.
- Bread crumbs
- Soak up tomato liquid to thicken the mixture and form a crisp, browned topping.
- Butter
- Coats the crumbs so they brown in the oven and add richness.
- Grated onion
- Adds aromatic flavor that blends into the tomato base.
The step that matters
Baking until brown. Baking long enough lets the buttered crumbs toast and brown on top, which gives the dish its crisp contrast to the soft tomato layer. Stopping too early leaves the topping pale and soggy.
Swap the onion
How well each one fits the dish's main ingredients (tomato, bread, pepper, butter):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Onionthe original
Fit is the average pairing score against tomato, bread, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
