Why it works: Eggplant and pepper are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,123 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Egg Plant
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the eggplant
Cut the eggplant in half lengthwise and carefully remove the flesh without damaging the shell.
Boil the eggplant in salted water until tender.
While cooking, decorate the shell by notching or scalloping the edges with a sharp knife.
Fill and bake
Drain the eggplant and mix the flesh with the beaten egg, chopped onion, sugar, butter, pepper, and salt.
Return the mixture to the shell and place it in a 400°F (200°C) oven to brown well.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggplant
- Forms the edible shell and soft, moist filling base once cooked and drained.
- Egg
- Binds the mashed eggplant filling so it holds its shape when baked.
- Onion
- Adds savory flavor and moisture to the filling.
- Butter
- Adds fat for richness and helps the top brown in the oven.
- Sugar
- Adds sweetness and promotes browning on the surface.
The step that matters
Drain the eggplant well before filling. Excess water from the boiled flesh thins the mixture and keeps the egg from setting firmly, so the filling can become loose and soggy in the oven.
Swap the onion
How well each one fits the dish's main ingredients (eggplant, egg, sugar, butter, pepper):
- Capsicumfits better
- Spinachfits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against eggplant, egg, sugar, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
