Directions
Prepare the liver
Wash the liver well.

Fry the ham and liver
Cut the ham into small pieces.

Remove the ham from the pan.
Keep the ham warm.
Fry the liver slices in the same pan for about 8 minutes.
Turn the liver slices once during frying.
Make the sauce and serve
In the remaining fat, add 1 tablespoon of flour, a little pepper, and salt.
Stir the mixture until it is combined.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Forms the main body of the dish and provides its rich, distinctive flavor.
- Flour
- Coats the liver for light browning and thickens the sauce.
- Pork ham
- Its fat renders into the pan for frying and its pieces add savory flavor.
- Ketchup
- Adds sweetness and acidity to the sauce.
The step that matters
Fry the liver for about 8 minutes and turn it once. Liver is lean and becomes dry and tough when overcooked, so timing matters. Turning it once cooks both sides evenly without overworking the surface.
