Ingredients
Directions
Prepare
Skin the liver and soak it in cold water to remove blood.
Slice the liver thinly, season with salt and pepper, and roll in flour.
Cook and serve
Fry the bacon in a skillet until crispy, then remove it.
In the same skillet, fry the liver, adding water and covering for a few minutes to keep it tender.
Serve the liver with the bacon.

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; cooks quickly and turns firm or dry if overcooked.
- Bacon
- Adds salty, savoury fat and crisp texture to the dish.
- Flour
- Dry coating that helps the liver brown in the pan.
- Water
- Added to the skillet with a lid to create steam that keeps the liver tender.
The step that matters
Frying the liver. Liver is lean and delicate, so brief cooking over moderate heat keeps it tender. Overcooking makes it tough and grainy as its proteins tighten. The added water and covering help gentle steaming.
