Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Fish and Tomato Pie
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
Fillet the fish, wash it, and wipe it well.
Grease a pie dish and place a layer of fish in it.
Assemble
Cover the fish with a layer of sliced tomatoes.
Sprinkle with salt, pepper, and sugar, then repeat the layers.
Add water and cover with greased paper.
Bake
Bake for 30 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the pie, becoming flaky and tender as it cooks.
- Tomatoes
- Add moisture and acidity that flavour the layers and keep the fish moist.
- Sugar
- Balances the acidity of the tomatoes and adds gentle sweetness.
The step that matters
Cover with greased paper before baking. The paper traps steam so the fish cooks gently in its own juices and the water and tomatoes stay in the dish instead of drying out. Greasing it keeps it from sticking.
Swap the tomato
How well each one fits the dish's main ingredients (fish, sugar, pepper, butter):
- Capsicumfits better
- Potatofits better
- Asparagusfits about as well
- Tomatothe original
Fit is the average pairing score against fish, sugar, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
