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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, moisture and tangy flavour of the sauce.
- Macaroni
- Forms the bulk of the dish and absorbs some of the sauce as it simmers.
- Butter
- Adds richness and carries flavour, and with the flour helps thicken the sauce.
- Flour
- Thickens the sauce when mixed with butter and blended into the tomatoes.
The step that matters
Mixing the butter and flour smooth before adding it. Flour added directly to hot liquid clumps, because its starch outside the granules gels before the rest dissolves. Blending it first with butter spreads the starch evenly so the sauce thickens smoothly.
Swap the tomato
How well each one fits the dish's main ingredients (onion, butter, flour, pepper, cheese):

- Tomatothe original
Fit is the average pairing score against onion, butter, flour, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
