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.
- Fine bread crumbs
- Absorb tomato juices and form a crisp, golden topping once browned.
- Butter
- Adds richness and helps the topping brown and taste savory.
- Minced onion
- Adds aromatic savory flavor that deepens during baking.
- Sugar
- Balances the acidity of the tomatoes and encourages browning.
The step that matters
Brown quickly under the broiler before serving. The broiler browns the crumb topping fast, and it can scorch in seconds. Watching closely keeps the top golden rather than burnt.
Swap the onion
How well each one fits the dish's main ingredients (tomato, bread, butter, pepper, sugar):
- Capsicumfits better
- Potatofits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against tomato, bread, butter, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
