Why it works: Pork and chicken match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 5,417 recipes. Both carry 2-furfurylthiol, which smells coffee, roasted. The science ↓
Chicken Livers
Ingredients
Directions
Make the base
Fry the chopped onion in butter over medium heat until nearly done, being careful not to scorch it.
Add the salt pork and cook until it is half done.
Cook the livers
Add the chicken livers, cover the pan, and cook slowly until well done and browned.
Season with salt and pepper, then remove the livers and arrange them on buttered toast.
Make the sauce and serve
Sprinkle flour into the pan drippings and let it cook until saturated but not scorched.
Pour in boiling water and season with salt and pepper, letting it boil until thickened.
Strain the sauce over the livers and serve with a border of rice and parsley.
Optionally, garnish with hard-boiled eggs cut into quarters.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken livers
- Form the main body of the dish, becoming tender and browned when cooked slowly covered.
- Butter
- Carries the onion and livers in the pan and adds richness and browning.
- Salt pork
- Adds savory fat and salty flavor to the pan drippings.
- Flour
- Thickens the pan drippings and boiling water into a smooth sauce.
- Onion
- Adds sweetness and aroma as it softens in butter.
The step that matters
Cooking the flour in the drippings. Flour must cook long enough to lose its raw starchy taste, but not scorch, which would make the sauce bitter and dark. Boiling the liquid afterward fully thickens the starch so the sauce sets smooth rather than pasty.
Swap the onion
How well each one fits the dish's main ingredients (butter, pork, chicken, liver, pepper, flour, rice):
- Potatofits better
- Capsicumfits about as well
- Onionthe original
- Asparagusfits about as well
Fit is the average pairing score against butter, pork, chicken, liver, pepper, flour, rice. Candidates are from the same food group and used in at least 100 recipes.
