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 ↓
Tripe and Tomatoes
Ingredients
Directions
Prepare the tripe
Cut the tripe into neat pieces and place it in cold water.
Bring to a boil and let it boil for 5 minutes.
Transfer the tripe to cold water and wash and scrape it well.
Make the sauce
Slice the tomatoes and rub them through a sieve.
Mix with the stock or water, and season with pepper and salt.
Pour the mixture into a saucepan, add the sliced onion and the tripe, and bring to a boil.
Simmer gently for 4 hours.
Mix the cornflour smoothly with a little water or stock, then pour it into the saucepan.
Stir until it boils.
Serve
Carefully dish the tripe, season and flavor the sauce to taste, and pour it over the tripe.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Main protein that becomes tender through long, gentle simmering.
- Tomatoes
- Provide acidity, body and bright flavor to the sauce once sieved.
- Cornflour
- Thickens the sauce into a smooth coating as it comes to a boil.
- Onion
- Adds savory aromatic flavor to the simmering sauce.
The step that matters
Simmer gently for 4 hours. A gentle, low simmer softens tripe slowly; a hard boil toughens its proteins and can make the sauce reduce or scorch unevenly.
