Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh tomatoes
- Provide the bulk and juice that moistens the layered casserole as it bakes.
- Fresh soft breadcrumbs
- Form a crumb topping that absorbs juices and browns in the oven.
- Butter
- Adds richness and flavor to the onion and helps the crumbs brown.
- Olive oil
- Adds fat that carries flavor and helps the topping brown.
The step that matters
Uncover for the final bake. Covering traps steam so the crumbs stay soft; uncovering lets moisture escape and the breadcrumb topping brown and crisp.

Fit is the average pairing score against butter, parsley, sauce, tomato, olive. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
