Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Renders fat for frying and adds salty, smoky flavor to the dish.
- Calves' liver
- Forms the main dish; frying browns its surface and sets a firm, tender texture.
- Flour
- Coats the liver for browning and later thickens the gravy as it cooks in the pan.
The step that matters
Frying the liver slowly. Liver turns tough and dry when overcooked. Slow frying over moderate heat browns the flour coating while keeping the inside tender.
