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 ↓
Stewed Calf's Liver
Ingredients
Directions
Prepare the liver
Cut the liver into dice and soak in cold water for 10 minutes.
Dry the liver pieces with cloths, season with salt and pepper, and dredge with flour.
Cook the liver and onion
Heat the butter in a saucepan and fry the sliced onion until golden, then remove the onion.
Fry the liver in the butter until light brown.
Add the stock, cover, and simmer for 30 minutes.
Remove the liver and keep warm on a platter.
Make the gravy and serve
Thicken the gravy with browned flour, then season with salt, parsley, ketchup, and lemon juice.
Bring to a boil, add sherry, and pour over the liver.
Add champignons if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Forms the main body of the dish and becomes tender with gentle simmering.
- Flour
- Coats the liver and, once browned, thickens the gravy.
- Butter
- Fat for frying that adds richness and browns the liver and onion.
- Sherry
- Adds acidity and aroma to the finished gravy.
- Stock
- Liquid that simmers the liver and forms the base of the gravy.
The step that matters
Frying the floured liver. Liver overcooks quickly and turns tough and grainy. Frying only until light brown, then simmering gently, keeps it tender and prevents the flour coating from scorching.
