Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers
Provide the main bulk and a fresh, watery body that softens when boiled.
Tomatoes
Add moisture and acidity, thickening into a sauce as they cook down.
Onion
Adds savory depth and aroma as it softens.
Bread crumbs
Absorb excess liquid and thicken the mixture, then brown on top.
Butter
Adds fat and richness and helps the crumb topping brown.

The step that matters

Boil until done. Tomatoes and cucumbers release a lot of water. Cooking them down until thickened keeps the bake from being soupy, and the bread crumbs can only absorb so much liquid.

Swap the cucumber

How well each one fits the dish's main ingredients (onion, tomato, pepper, bread, butter):
