Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's liver
- Forms the main body of the dish, cooked quickly to stay tender and browned on the outside.
- Bacon
- Its drippings fry the liver and add savory, salty fat flavor.
- Onions
- Fried until brown, they add sweetness and deep browned flavor.
- Ghee
- Adds fat for frying the liver and supports browning in the pan.
The step that matters
Frying the liver slices. Liver is lean and dense, so brief, high-heat frying browns the surface while keeping the inside tender. Overcooking makes it dry, firm and grainy.
Swap the onion
How well each one fits the dish's main ingredients (liver, pepper, ghee):

Fit is the average pairing score against liver, pepper, ghee. Candidates are from the same food group and used in at least 100 recipes.
