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 says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Scald and peel the tomatoes.
Butter a baking dish and cover the bottom with a layer of tomatoes cut into ½-inch slices.
Layer and season
Season with coarse sea salt, pepper, and a sprinkle of sugar.
Cover with a thin layer of buttered bread crumbs (add onion juice for improvement).
Repeat the layers, finishing with crumbs on top.
Optionally, add a layer of grated cheese between the tomato layers.
Bake
Bake in a hot oven at 400°F (200°C) for one hour, less time for a smaller quantity.

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 juice that softens and flavors the dish as it bakes.
- Bread crumbs
- Absorb tomato juice and form a soft, lightly browned crust on top.
- Butter
- Adds richness and helps the crumbs brown in the oven.
- Sugar
- Balances the acidity of the tomatoes with a touch of sweetness.
The step that matters
Bake in a hot oven. Baking at a high temperature for the full time lets the tomato juice reduce and thicken slightly, while the crumbs brown. Too little time leaves the dish watery and pale.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (tomato, butter, pepper, sugar, bread, cheese):
- Capsicumfits better
- Potatofits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against tomato, butter, pepper, sugar, bread, cheese. Candidates are from the same food group and used in at least 100 recipes.
