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 ↓
Kidney Beans a LA Lyonnaise
Ingredients
Directions
Prepare the beans
Soak the kidney beans overnight, then boil them until tender, but not breaking.
Drain the beans thoroughly and sprinkle with salt.
Let them dry in a colander over an empty pot.
Cook and serve
In a frying pan, heat the clarified dripping with the grated onion and chopped parsley.
Add salt and pepper to taste.
When the mixture is hissing hot, add the beans.
Shake the pan over the heat for about two minutes until well mixed and hot, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidney beans
- Form the main body of the dish and hold their shape when cooked until tender.
- Clarified dripping
- Provides fat for frying, carrying flavour and giving the beans a rich coating.
- Onion
- Adds aromatic sweetness and savoury depth as it softens in the hot fat.
The step that matters
Drain and dry the beans thoroughly before frying. Surface water would cool the hot fat and steam the beans instead of letting them warm and coat evenly in the dripping. Drying first keeps the fat hot and the beans intact.
Swap the kidney beans
How well each one fits the dish's main ingredients (beef, onion, parsley, pepper):
- Black-eyed peafits better
- Chickpeafits better
- Beansfits better
- Kidney beansthe original
Fit is the average pairing score against beef, onion, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
