Fried Liver, with Brown Sauce
Ingredients
Directions
Prepare the liver
Cover the liver slices with boiling water and let stand for 5 minutes.
Remove from water and wipe dry, then dredge with flour, salt, and pepper.
Fry and make the sauce
In a frying pan, cook the bacon until crispy, then add the liver and fry until brown on both sides.
Place the liver and bacon on a hot dish.
In the same pan, add 1 tablespoon of flour to the grease and stir until brown.
Pour in the soup stock, Worcestershire sauce, and mushroom ketchup, adding salt to taste.
Pour the sauce over the liver and serve.

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, browned on the outside while staying tender inside.
- Flour
- Dry coating that browns in the frying fat and thickens the sauce.
- Fat bacon
- Adds fat and savory flavor to the pan for frying the liver and browning the flour.
- Soup stock
- Liquid base of the brown sauce, carrying the flavor and thinning the roux.
- Worcestershire sauce
- Adds tangy, savory depth to the sauce.
The step that matters
Browning the flour in the fat. Flour must be stirred until evenly brown in the bacon grease before the stock goes in. Cooking it long enough removes raw starch taste and builds color and nutty flavor, and it thickens the sauce more smoothly when liquid is added gradually.
