Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tripe Lyons Fashion
Ingredients
Directions
Prepare
Cut the tripe into thin slices about 1 inch square and wipe very dry.
Mince the onions and place them with the butter in a frying pan.
Cook
Brown the onions slowly; when they are about half done, add the tripe.
Fry the tripe for 10 minutes, then season with salt, pepper, and vinegar.
Optionally, add oysters and cook just until plump.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Cooked tripe provides the chewy, tender main body of the dish.
- Onions
- Slow browning turns the onions sweet and deeply flavoured, forming the base of the dish.
- Butter
- Butter carries the cooking of the onions and tripe and adds richness and browning.
- Vinegar
- A splash of acid at the end brightens the rich butter and onion flavours.
The step that matters
Dry the tripe before frying. Wiping the tripe very dry lets its surface brown in the hot fat instead of steaming in released moisture, so it gains flavour and texture.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper, vinegar):
- Capsicumfits better
- Mustardfits better
- Cabbagefits about as well
- Onionthe original
Fit is the average pairing score against butter, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
