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
- Broken macaroni
- Forms the bulk of the dish and absorbs the stock as it cooks, becoming tender.
- Onion
- Softens and browns in the fat, adding sweetness and savory depth.
- Tomato
- Breaks down during cooking, adding acidity and moisture that flavors the macaroni.
- Lard or butter
- Fat that carries flavor and helps the macaroni and vegetables brown lightly.
The step that matters
Stir until slightly browned. Browning the macaroni and onion in fat builds savory flavor through the Maillard reaction. Stopping at slight color keeps the pasta from turning bitter or scorched before liquid is added.
Swap the tomato
How well each one fits the dish's main ingredients (butter, onion, pepper):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against butter, onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
