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 Tomato
Ingredients
Directions
Prepare
Break the macaroni into pieces.
Fill a dry soup tureen one third full with the broken macaroni.
Rinse the macaroni and soak it in cold water for one hour.
Boil the tomatoes in a covered saucepan for ten minutes.
Make the sauce
In a large kettle, bring water to a boil.
Add 2 tablespoons of salt to the boiling water.
Add the macaroni to the boiling water and cook for twenty minutes or until tender.
Cream the butter.
Beat in the flour until smooth.
Strain the boiled tomatoes.
Press the strained tomatoes through a strainer to remove skins and seeds.
Return the strained tomatoes to the pan. Boil again.
Stir in the butter mixture until smooth.
Season the sauce with salt and pepper.
Serve
Drain the macaroni in a colander and transfer it to the tureen.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 its starchy, chewy body once cooked until tender.
- Tomatoes
- Supply the main body, acidity and flavour of the sauce once boiled and strained.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Flour
- Thickens the sauce when beaten in with the butter, giving it body.
The step that matters
Beat the flour into the butter until smooth. Lumps of flour that are not fully worked into the butter will stay in the sauce as dry specks. Blending them smooth first lets the flour thicken the sauce evenly when it meets the hot tomatoes.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, pepper, parmesan cheese):
- Spinachfits better
- Asparagusfits better
- Chivefits about as well
- Tomatothe original
Fit is the average pairing score against butter, flour, pepper, parmesan cheese. Candidates are from the same food group and used in at least 100 recipes.
