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 ↓
Baked Tomatoes
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash and wipe the tomatoes, then remove a thin slice from the stem ends.
Scoop out the seeds and pulp.
Fill and bake
Mix the pulp with an equal amount of cracker crumbs, salt, pepper, onion juice, and sugar.
Refill the tomatoes with the mixture and place them in a buttered baking dish.
Sprinkle with buttered crumbs and bake at 400°F (200°C) for 25 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the juicy vessel and body of the dish, softening as they bake.
- Cracker crumbs
- Absorb tomato juice and bind the pulp into a spoonable, set filling.
- Sugar
- Adds sweetness that balances the acidity of the tomatoes.
- Buttered crumbs
- Add a golden, crisp topping as the surface browns in the oven.
The step that matters
Filling the tomatoes with the pulp mixture. Tomato pulp is watery, and cracker crumbs must be mixed in evenly so the filling holds its shape rather than leaking or turning soggy during baking.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, sugar, butter):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
