Calf's Liver and Bacon
Ingredients
Directions
Prepare and fry
Cut the calf liver into thin slices.
Cut an equal number of bacon slices.
Fry the bacon in a pan until cooked, then place it on a hot dish.
Fry the liver slices in the bacon fat, seasoning with pepper and salt and dredging lightly in flour.
Turn the liver occasionally to prevent burning.
Make the sauce and serve
When done, arrange the liver slices on the dish with a bacon slice between each.
Pour off the bacon fat.
Add a small piece of butter, dredge in a little flour, add lemon juice and water, and bring to a boil.
Pour the sauce into the center of the dish.
Optionally garnish with lemon slices or forcemeat balls.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf liver (in the method)
- Main protein that turns tender and juicy when cooked briefly.
- Bacon
- Adds salty, savoury fat that flavours and crisps the liver.
- Béchamel sauce
- Creamy base that adds richness and moisture to the dish.
- Lemon juice
- Adds acidity that brightens the rich liver and sauce.
- Flour (in the method)
- Light coating that helps the liver brown and thickens the sauce.
The step that matters
Frying the liver. Liver toughens and dries out when overcooked, so brief frying over steady heat keeps it tender. Turning the slices occasionally cooks them evenly and stops the edges from scorching.
