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 ↓

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
- Butter
- Adds fat and richness, carrying flavor into the sauce.
- Flour
- Thickens the sauce as it cooks with the butter and tomatoes.
- Canned tomatoes
- Form the base of the sauce, supplying most of its liquid and flavor.
The step that matters
Stir in the flour until the mixture bubbles. Cooking the flour in melted butter drives off raw starch taste and lets it thicken evenly; adding it without stirring can leave lumps.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, pepper, sugar):
- Capsicumfits better
- Arrowrootfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against butter, flour, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
