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 ↓

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 cooks down under the crumbs.
- Bread crumbs
- Absorb tomato juices and form a crisp, golden topping as they brown.
- Butter
- Adds richness and helps the crumbs brown evenly in the oven.
- Sugar
- Balances the acidity of the tomatoes and encourages browning on the top.
The step that matters
Bake covered, then uncover. Baking covered first traps steam so the tomatoes cook through; uncovering then lets moisture escape so the crumbs can brown rather than stay soggy.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, bread, butter, sugar):
- Capsicumfits better
- Potatofits about as well
- Sweet potatofits about as well
- Tomatothe original
Fit is the average pairing score against pepper, bread, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
