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 removing the tops and scooping out the pulp.
Mix the pulp with an equal quantity of cracker crumbs.
Season the mixture with butter, pepper, coarse sea salt, and chopped onion.
Bake
Fill the tomato shells with the mixture and replace the tops.
Bake in a hot oven at 400°F (200°C) for 70 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the shell that holds the filling and softens into a juicy base as it bakes.
- Cracker crumbs
- Absorb the tomato pulp juices and bind the filling so it holds its shape.
- Butter
- Adds richness and fat, helping the filling brown lightly on top in the oven.
- Chopped onion
- Contributes savory aroma and a mild sharpness that softens during baking.
The step that matters
Filling the shells. Packing the filling too loosely or overfilling can cause spilling or uneven cooking. The mixture should be moist enough to bind with the crumbs but not so wet that it leaks out of the tomato shells 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.
