Why it works: Pepper and tomato 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 ↓
Stewed Pigs Feet
Ingredients
Directions
Prepare the feet
Boil the pigs feet with bay leaf, pepper, and salt until tender.
Remove the bones and cut the meat into 2-inch pieces.
Make the sauce and finish
In a pan, heat the butter, then add flour, onion, tomatoes, and boiling water.
Cook for about 15 minutes.
Add the pigs feet, season well, and cook for an additional 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pigs feet
- Provide the main meat, which becomes tender through boiling and then further cooking in the sauce.
- Tomatoes
- Add acidity and body to the sauce as it cooks down.
- Flour
- Thickens the sauce by binding with the butter and liquid.
- Butter
- Adds fat and richness to the sauce and carries flavor.
The step that matters
Boil the pigs feet until tender. Pig's feet are rich in collagen, which needs long, gentle cooking to break down into gelatin. Cooking too briefly leaves the meat tough and the texture unpleasant, so the feet should be fully tender before the sauce step.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, onion, butter, flour):
- Chivefits better
- Okrafits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against pepper, onion, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
