Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Sheep's Liver, Fried
Ingredients
Directions
Prepare the liver
Soak the liver and cut it into slices ⅓ inch thick.
Dry each slice thoroughly with a soft cloth.
Flour the slices well and sprinkle with pepper, salt, and chopped parsley.
Fry the liver
Heat dripping in a frying pan and add the liver slices.
Fry gently until tender, turning occasionally for even cooking.
Once cooked, lift the liver onto a hot dish and pour off excess fat from the pan.
Make the gravy and serve
Mix flour with a little cold water, then add boiling stock or water.
Pour the mixture into the pan and stir briskly until it boils.
Add browning sauce, store sauce, and additional pepper and salt.
Let it boil for 1-2 minutes, then strain over the liver.
Serve very hot, optionally topped with fried onion.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's liver
- Is the main dish, cooked through and turned tender by gentle frying.
- Flour
- Coats the slices so they brown lightly and later thickens the gravy.
- Dripping or oil
- Conducts heat in the pan and gives the slices a fried surface and flavour.
- Stock or water
- Forms the liquid base of the gravy that thickens as it boils.
- Browning sauce
- Adds colour and savoury depth to the gravy.
The step that matters
Fry gently until tender. Liver is lean and cooks quickly; high heat or overcooking toughens its proteins and makes it dry and grainy, so gentle heat and careful timing keep it tender.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (liver, flour, pepper, parsley, sauce):
- Shallotfits better
- Carrotfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against liver, flour, pepper, parsley, sauce. Candidates are from the same food group and used in at least 100 recipes.
