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 ↓
Baked 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
Preheat the oven to 400°F (200°C).
Skin the tomatoes and remove the hard centers.
Place the tomatoes in a baking pan.
Fill and bake
In each tomato cavity, add minced onion, sugar, moistened bread crumbs, and pepper.
Scatter grated bread crumbs thickly over the tops, filling in the spaces.
Top with small pieces of butter.
Sprinkle with sugar, salt, and pepper.
Bake until browned on top, about 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the edible shell that softens and holds the filling while baking.
- Bread crumbs
- Absorb juices and form a filling that stays moist, then crisp and brown on top.
- Butter
- Melts over the crumbs, adding richness and helping the topping brown.
- Sugar
- Adds sweetness and helps the tomato tops caramelize and brown.
- Onion
- Adds savory aroma and flavor to the tomato filling as it cooks.
The step that matters
Bake until browned on top. The topping needs enough heat to brown without drying out. Watch the crumbs closely, since the sugar and butter can scorch while the tomatoes are still soft inside.
Swap the onion
How well each one fits the dish's main ingredients (tomato, sugar, bread, pepper, butter):
- Capsicumfits better

- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against tomato, sugar, bread, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
