Why it works: Tomato and potato match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,798 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Green Tomato Stew
Ingredients
Directions
Prepare

Thicken and serve
Thicken with a little flour mixed with cold water.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the main body and tart flavour of the stew.
- Potatoes
- Soften during cooking and help give the stew body and substance.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished stew.
- Flour
- Thickens the cooking liquid as starch swells with heat.
The step that matters
Thickening with flour. Flour must be mixed with cold water before being added, so it disperses without lumps. Starch thickens the liquid only when it heats, so the stew should be simmering when it is stirred in.
Swap the tomato
How well each one fits the dish's main ingredients (potato, pepper, butter, flour):
- Chivefits better
- Spinachfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against potato, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
