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 ↓
Stuffed Tomatoes with Macaroni
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
Preheat the oven to 400°F (200°C).
Select smooth and firm tomatoes and scoop out the seeds.
Fill and bake
Fill the cavities with cooked macaroni.
Add salt, pepper, a bit of butter, and a little grated cheese.
Bake for thirty minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Hollow shells that hold the filling and soften as they bake.
- Cooked macaroni
- Fills the cavities and provides the bulk of the filling.
- Butter
- Adds richness and moisture to the filling as it melts.
- Grated cheese
- Melts and browns on top, adding savory flavor and a golden crust.
The step that matters
Scooping out the seeds. Removing the seeds and watery pulp leaves a firmer cavity, so the filling sits well and the tomato does not release excess liquid during baking.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, butter, cheese):
- Capsicumfits better
- Potatofits about as well
- Mustardfits about as well
- Tomatothe original
Fit is the average pairing score against pepper, butter, cheese. Candidates are from the same food group and used in at least 100 recipes.
