Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggplant
- Forms the hollow shell that holds the filling and softens when parboiled.
- Onions
- Forms an alternative hollow shell that turns sweet and soft as it cooks.
- Cheese
- Adds richness and body to the filling and browns on the surface in the oven.
- Raw egg
- Binds the filling so it holds its shape when stuffed and baked.
- Butter
- Adds fat and richness and helps the surface brown.
The step that matters
Parboil until tender. If the shells are undercooked they stay firm and bitter, and the filling will not bake through evenly. Parboiling softens the vegetable enough to scoop and stuff without tearing, while leaving it intact to hold the filling during baking.
Swap the eggplant
How well each one fits the dish's main ingredients (onion, cheese, egg, butter):
- Potatofits better
- Chivefits better
- Mustardfits better
- Eggplantthe original
Fit is the average pairing score against onion, cheese, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
