Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Forms the moist, rich liquid that keeps the layers tender as they bake.
- Eggplant
- Forms the main body of the dish, softening into tender layers as it bakes.
- Tomatoes
- Add moisture and gentle acidity that brightens the rich layers.
- Cooked spaghetti
- Adds starch and bulk that holds the layers together.
- Grated cheese
- Melts and browns on the surface, adding savory richness.
- Butter
- Adds fat that enriches flavor and promotes browning on top.
The step that matters
Bake gently for 1.5 hours. Low, slow heat lets the eggplant soften fully and the cream thicken without curdling or drying out. Baking too hot can scorch the top or make the cream separate, so the dish should be kept at a gentle, steady temperature.
Swap the eggplant
How well each one fits the dish's main ingredients (cream, tomato, cheese, butter, pepper):
- Capsicumfits better

Fit is the average pairing score against cream, tomato, cheese, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
