Why it works: Pepper and parsley 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 ↓
Lyonnaise Tripe
Ingredients
Directions
Prepare the tripe
Wipe the tripe and cut it into pieces.
Place the tripe in a blazer cover and let it stand for 1 minute to drain moisture.
Cook and serve
In a skillet, cook the butter and onion over medium heat until the onion is yellow.
Add the tripe to the skillet and cook for 8 minutes, adding more butter if necessary.
Season with salt and pepper, then sprinkle with parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the main body of the dish and gives it its chewy, tender texture when cooked.
- Butter
- Adds fat for richness and helps the tripe and onion brown in the pan.
- Onion
- Adds savory aroma and sweetness as it softens in the butter.
The step that matters
Cooking the tripe in the skillet. Tripe is already cooked when bought but needs enough heat and fat to brown lightly without drying out. Adding butter as needed keeps the surface from sticking and scorching, while the eight-minute cook lets the meat firm and develop flavor.
