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 half‑inch slices.
Layer and season
Season with coarse sea salt, black pepper, and a sprinkle of sugar.
Cover with a thin layer of buttered bread crumbs (add onion juice for improvement).
Fill the dish with layers, ensuring crumbs are on top.
Optionally, add a layer of grated cheese to each layer of tomato.
Bake
Bake at 400°F (200°C) for one hour, less time if using a small 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 moisture that softens and bakes into the dish.
- Butter
- Adds richness and helps the crumbs brown on top.
- Bread crumbs
- Form a topping that absorbs juices and browns as it bakes.
- Sugar
- Balances the acidity of the tomatoes with a touch of sweetness.
The step that matters
Bake at 400°F (200°C) for one hour, less time if using a small quantity.. Tomatoes release liquid as they heat. Baking long enough lets the liquid thicken slightly while the crumbs brown, while overbaking can dry the topping and make the dish watery or uneven.
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.
