Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Tripe Stew
Ingredients
Directions
Prepare the tripe
Wash the tripe well and cut it into strips.
Place the tripe in a small kettle and barely cover it with cold water.
Heat slowly.
Once boiling, transfer the tripe to a larger kettle.
Cook for five to six hours.
When the tripe is done, place it on a hot dish.
Make the sauce
In a separate pan, melt the butter. Mix in the flour to create a roux.
Add 1 cup of the cooking liquid, tomatoes, onion, salt, and paprika to the roux. Stir well.
Strain the sauce over the hot tripe.
Garnish with minced parsley and cooked peppers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the body of the stew and becomes tender through long, slow cooking.
- Flour
- Thickens the butter and cooking liquid into a smooth sauce as a roux.
- Butter
- Carries the flour for the roux and adds richness to the sauce.
- Tomatoes
- Add acidity and body to the sauce.
The step that matters
Cooking the tripe for five to six hours. Tripe is tough connective tissue, and it needs long, slow cooking at a gentle heat to break down and become tender. Cooking it too hard or too briefly leaves it chewy.
Swap the tomato
