Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Main protein; it is cooked briefly so it stays tender and does not toughen.
- Bacon
- Its rendered fat cooks the liver and forms the base of the sauce, adding savoury flavour.
- Flour
- Browns in the bacon drippings and thickens the sauce as it is moistened.
- Hot stock
- Liquid that dissolves the browned flour and turns the mixture into a pourable sauce.
- Lemon juice
- Adds acidity that brightens the rich liver, bacon and sauce.
The step that matters
Fry the liver slices until done. Calf's liver is lean and cooks quickly; overcooking makes it dry and grainy, while undercooking leaves it unpleasantly soft in the centre. Frying thin slices briefly keeps it tender.
