Why it works: Eggplant and tomato work together. They rank in the top 3% of all ingredient pairs, and cooks put them together in 651 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Baked Tomato and Eggplant
Ingredients
Directions
The book says “a hot oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Pour the cream into a deep earthenware dish.
Assemble
Cut the eggplant into very thin slices, salt them well, and line the dish with the slices.
Slice the tomatoes and place a layer on top of the eggplant.
Add a layer of macaroni, sprinkle with cheese and butter, and season with pepper.
Cover with another layer of tomatoes, season with salt and pepper, and add a top layer of eggplant, also seasoned.
Bake and serve
Bake gently for 1 hour and 20 minutes.
Serve in the same dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream
- Adds moisture and richness, helping the layers stay soft as they bake.
- Eggplant
- Forms the soft, tender layers that give the casserole its body.
- Tomatoes
- Add moisture and acidity that flavour the layers as they cook.
- Macaroni
- Provides starch and bulk, giving the casserole structure when baked.
- Cheese
- Melts and adds savoury richness and flavour to the layers.
- Butter
- Adds fat and richness, helping the top layers brown and taste rich.
The step that matters
Baking gently at low heat. A low oven temperature cooks the eggplant and macaroni through slowly, keeping the cream from curdling or drying out and making the layers tender.

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.
