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
Ingredients
Directions
Stew the tomatoes
Remove the stalks from the tomatoes and place them in a wide stewpan.
Pour the gravy over the tomatoes and stew gently until tender, turning occasionally.
Thicken and serve
In a small bowl, mix the butter and flour together to form a paste.
Add the paste to the stew and let it boil for 10 minutes.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, acidity and juice that the stew is built on.
- Gravy
- Supplies the liquid base and savoury flavour that the tomatoes cook in.
- Butter
- Adds fat for a richer mouthfeel and helps the flour blend smoothly.
- Flour
- Thickens the liquid as its starch swells and gelatinises during boiling.
The step that matters
Boiling the butter and flour paste into the stew. Flour thickens only when its starch is heated enough to swell. Adding the paste and boiling it for the full 10 minutes thickens the stew evenly and cooks out the raw floury taste. Stirring the paste in well helps prevent lumps.
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.
