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
Prepare the tomatoes by cutting off the tops and scooping out the pulp.
Mix the tomato pulp with cracker crumbs, butter, pepper, salt, and chopped onion.
Bake and serve
Fill the tomato shells with the mixture and replace the tops.
Bake in a 400°F (200°C) oven for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the edible shells and release juice that moistens the filling as they bake.
- Cracker crumbs
- Absorb tomato juice and bind the filling so it holds its shape.
- Butter
- Adds fat and richness, helping the filling brown lightly on top.
- Chopped onion
- Contributes savory aroma and a mild sharpness to the filling.
The step that matters
Scooping out the tomato pulp. Cutting the shells cleanly and leaving them intact keeps the walls sturdy enough to hold the filling. Scooping too deeply can puncture the shell, so the filling may leak during baking.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper, onion):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against butter, pepper, onion. Candidates are from the same food group and used in at least 100 recipes.
