Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Egg Plant and Green Peppers
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Peel and cut the eggplant into cubes.
Parboil the eggplant for 20 minutes, then drain.
Assemble and bake
In a baking dish, layer the eggplant with buttered bread crumbs and minced green peppers.
Pour the white sauce over the layers.
Cover the top with more crumbs and bits of butter.
Bake covered in a 350°F (175°C) oven.
Remove the cover and let it brown before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggplant
- Forms the bulk of the dish and turns soft and tender when parboiled and baked.
- White sauce
- Adds moisture and a creamy binding that keeps the layers from drying out in the oven.
- Buttered bread crumbs
- Add a crisp, golden topping and absorb some moisture as the dish bakes.
- Butter
- Adds richness and helps the crumb topping brown.
- Finely minced green peppers
- Contribute a fresh, slightly bitter aroma and some moisture to the layers.
The step that matters
Remove the cover and let it brown before serving. The cover traps steam, which keeps the dish moist but pale. Uncovering lets surface moisture evaporate, so the crumbs and butter can toast and brown through Maillard reactions.
Swap the eggplant
How well each one fits the dish's main ingredients (bread, pepper, sauce, butter):
- Capsicumfits better

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