Stewed Liver and Bacon
Ingredients
Directions
Prepare the liver
Wash the liver and cut it into small, thin pieces.
Roll the liver pieces in flour, pepper, and salt.
Cook the bacon and brown the liver
In a frying pan, cook the bacon until crispy, then remove it.
In the bacon fat, quickly brown the liver pieces.
Stew and serve
Transfer the liver to a stewpan, add water and sauces, and cook slowly for 2 hours.
Warm the bacon just before serving and garnish the dish with it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Provides the main body and rich flavour of the dish, becoming tender with slow stewing.
- Bacon
- Adds salty, smoky fat for browning the liver and a crisp garnish.
- Flour
- Coats the liver pieces, helping them brown and thickening the stewing liquid.
- Mushroom ketchup
- Adds savoury, umami depth to the stewing liquid.
- Worcestershire sauce
- Adds savoury, tangy depth that rounds out the stewing liquid.
The step that matters
Quickly brown the liver in the bacon fat. Searing the floured liver briefly over high heat builds browned flavour on the surface. Overcooking at this stage toughens the liver before the slow stew even begins.
