Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- The main ingredient, providing the dish's rich, meaty flavor and tender texture when cooked briefly.
- Flour
- Coats the liver so it browns in the pan and forms a lightly crisp surface.
- Sliced bacon
- Renders fat for frying the liver and adds smoky, savoury flavor.
The step that matters
Adding the liver to the hot bacon fat. Liver is lean and delicate, so it overcooks quickly and turns dry and grainy. A brief, hot sear browns the flour coating while keeping the inside tender.
