Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Calf's liver: Is the main ingredient, cooked to a browned, fully cooked finish.
Flour: Coats the slices so they brown in the fat and form a light crust.
Lard or dripping: Conducts heat for frying and adds richness and browning to the surface.

The step that matters

Fry the liver in lard or dripping until browned and thoroughly cooked. Liver is thin and cooks quickly, so high heat browns the flour coating before the interior overcooks and turns tough and dry. Frying until thoroughly cooked is still needed for safety, so watch color and time closely.
