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 ↓
Macaroni and Tomatoes
Ingredients
Directions
Cook the macaroni
Break the macaroni into short lengths.
Put it into rapidly boiling salted water and cook until tender.
Make the tomato sauce
Prepare 1 pint of tomato puree by passing the tomatoes through a fine sieve.
Melt the butter in a saucepan, add the flour, and cook for a few minutes.
Stir in the tomato puree, a good pinch of sugar, and season to taste.
Let it boil for a few minutes, then add the macaroni.
When thoroughly hot, turn onto a dish and serve.

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 provides the starchy body of the meal.
- Tomatoes
- Supply the main flavour, acidity and moisture of the sauce.
- Butter
- Adds richness and fat to the sauce and carries flavour.
- Flour
- Cooked with the butter to form a roux that thickens the tomato sauce.
- Sugar
- Softens the sharpness of the tomatoes with a touch of sweetness.
The step that matters
Cooking the roux. Flour must cook in the melted butter for a few minutes to lose its raw taste and to thicken the sauce evenly. Adding the tomato puree before this cooking is done can leave lumps and a floury flavour.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, sugar, pepper):
- Capsicumfits better
- Arrowrootfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against butter, flour, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
