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 ↓
Italian Macaroni and Tomatoes
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Cook the macaroni
Boil the macaroni until tender.
Drain the macaroni and place it in a saucepan with butter, coarse sea salt, and pepper.
Make the tomato macaroni
Add the tomato pulp and simmer for 15 minutes.
Sprinkle with grated cheese and serve hot.
Alternatively, layer the tomato and macaroni in a dish with breadcrumbs, cheese, and seasoning, topping with breadcrumbs and bits of butter.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and absorbs the tomato and butter as it cooks.
- Tomato pulp
- Provides moisture and bright acidity that flavour the pasta as it simmers.
- Butter
- Adds fat and richness, coating the macaroni and carrying flavour.
- Grated cheese
- Adds savoury flavour and melts into a creamy, binding layer.
- Breadcrumbs
- Form a crisp, golden topping when baked.
The step that matters
Simmering the tomato pulp. Simmering for the full 15 minutes lets the pulp thicken and reduce, so the sauce clings to the macaroni rather than pooling and making the dish watery.
Swap the tomato
How well each one fits the dish's main ingredients (cheese, butter, pepper):
- Capsicumfits better
- Potatofits about as well
- Mustardfits about as well
- Tomatothe original
Fit is the average pairing score against cheese, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
