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 ↓
Tomatoes Stewed in Butter
Ingredients
Directions
In a saucepan, melt a large lump of butter.
Dredge the butter with ½ teaspoon of flour.
Carefully pour in ⅔ cup of canned tomatoes or 1 cup of sliced fresh tomatoes without disturbing the butter.
Sprinkle with salt and pepper, and add 1 teaspoon of flour.
Cover and cook gently for 25 minutes without stirring.
Use an earthenware dish that can be served at the table.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce with fat and adds a rich, rounded flavour.
- Flour
- Thickens the juices that form as the tomatoes cook, giving the dish body.
- Tomatoes
- Provide the main body, moisture and acidity of the dish.
The step that matters
Cover and cook gently without stirring. Gentle, covered heat lets the tomatoes soften and release juices slowly, while stirring would break them up and can cause the flour to clump, leaving the sauce uneven.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, pepper):
- Shallotfits better
- Chivefits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
