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 ↓
Baked 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
Open a can of tomatoes and pour them into a bowl.
After an hour, season with sugar, salt, pepper, and butter cut into small bits rolled in flour.
Distribute the butter evenly throughout the tomatoes.
Cover with dry bread crumbs.
Bake and brown
Bake in a covered pudding dish at 350°F (175°C) for about 30 minutes.
Remove the cover and brown on the upper rack of the oven.
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.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the juicy base and supply the sharp, acidic flavor of the dish.
- Butter
- Adds fat and richness, and helps the top brown as it melts.
- Sugar
- Adds sweetness that balances the acidity of the tomatoes.
- Dry bread crumbs
- Form a crisp topping that browns in the oven and absorbs some liquid.
The step that matters
Remove the cover and brown on the upper rack. The covered dish traps steam so the tomatoes cook through. Uncovering lets surface moisture evaporate, so the crumbs and butter can brown. Leaving the cover on too long leaves the top pale and soft.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, pepper, butter, flour, bread):
- Capsicumfits better
- Shallotfits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against sugar, pepper, butter, flour, bread. Candidates are from the same food group and used in at least 100 recipes.
