Why it works: Pepper and mushroom are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 13,580 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Fried Calves’ Liver
Ingredients
Directions
Prepare the liver
Cut the calves’ liver into slices ¼ inch thick.
Dip each slice in a mixture of flour, salt, and pepper.
Fry the liver and bacon
Heat drippings in a frying pan until very hot, then add the liver.
Cook for 5 minutes, then turn the liver and cook until done.
In another pan, crisp and brown the bacon cut into thin slices.
Remove most of the fat from both pans, leaving a little in the liver pan.
Make the gravy and serve
Stir in 1 tablespoon of flour and dilute with water or stock until smooth.
Season with salt, pepper, and mushroom ketchup, then stir in minced gherkins.
Place the liver on a hot platter, pour the gravy around it, and garnish with bacon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves’ liver
- Forms the main body of the dish, cooked quickly so it stays tender inside.
- Flour
- Coats the slices so they brown in the fat, and thickens the gravy.
- Bacon
- Adds crisp texture and savory fat that flavors the dish.
- Mushroom ketchup
- Adds deep savory flavor to the gravy.
- Minced gherkins
- Adds sharp acidity that balances the rich liver and gravy.
The step that matters
Heat the drippings until very hot before adding the liver. A very hot pan sears the flour-coated surface quickly, creating browning and a crust while the inside stays tender. Liver overcooks easily, so it is best cooked briefly over high heat.
