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 liquid base and acidic, savory body of the soup.
- Cheese
- Melts into the tomato base to add richness and savory flavor.
- Macaroni
- Adds starch and bulk, absorbing some of the broth as it sits.
The step that matters
Simmer for 30 minutes before serving. Long simmering lets the macaroni soften further and absorb liquid, so the soup thickens. Pasta left too long can turn mushy, so timing matters.
Swap the tomato
How well each one fits the dish's main ingredients (cheese, pepper):
- Capsicumfits better
- Mustardfits about as well
- Tomatothe original
- Spinachfits less well
Fit is the average pairing score against cheese, pepper. Candidates are from the same food group and used in at least 100 recipes.
