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
Prepare
Remove the stalks from the tomatoes and place them in a wide stewpan.
Stew and thicken
Pour the brown gravy over the tomatoes and stew gently until tender, turning occasionally.
In a small bowl, mix the butter and flour to form a paste, then add to the stew.
Let the mixture boil for 10 minutes after adding the thickening.
Serve
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 and bulk, softening into the stew as they cook.
- Brown gravy
- Supplies the liquid and savoury flavour that the tomatoes stew in.
- Butter
- Adds richness and carries flour into the stew smoothly as a paste.
- Flour
- Thickens the stew as its starch swells when heated with the liquid.
The step that matters
Adding the flour and butter paste. Flour lumps if dropped in dry. Mixing it with butter into a smooth paste first lets the starch disperse evenly, so it thickens the liquid without clumps once it is boiled.
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.
