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
- Form the main body of the dish and release juices that concentrate as they cook.
- Butter
- Adds fat for frying and carries flavor while helping the tomato surfaces brown.
- Lard
- Provides a high-heat frying fat that promotes even browning on the cut surfaces.
- Flour
- Forms a light coating that helps the surfaces brown and develop a crisp crust.
The step that matters
Let the tomatoes brown thoroughly. Browning comes from Maillard reactions between sugars and proteins at the surface, which need sustained high heat and little moisture. Rushing this step leaves the tomatoes pale and steamed rather than deeply caramelized.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper, flour):
- Shallotfits better
- Chivefits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
