Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Supply the juicy body of the dish, releasing liquid that moistens and softens the layers as they bake.
- Bread or cracker crumbs
- Absorb the tomato juices and give the layers body, while the top layer crisps and browns.
- Sugar
- Adds sweetness that balances the acidity of the tomatoes.
The step that matters
Removing the cover to brown the top. Baking covered traps steam, which keeps the tomatoes moist and cooks them through. Uncovering lets surface moisture evaporate, so the crumbs can brown and crisp. Uncovering too early leaves the top pale and soggy.
Swap the tomato
How well each one fits the dish's main ingredients (bread, pepper, sugar):
- Capsicumfits better
- Tomatothe original
- Mustardfits about as well
- Sweet potatofits about as well
Fit is the average pairing score against bread, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
