Why it works: Parsley and pepper 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 ↓
Calf’s Liver Minced
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the mince
Blanch the calf's liver.
Chop the liver with veal suet, onion, truffles, parsley, sweet herbs, bread crumbs, salt, and pepper.
Bind the mixture with eggs and cream.
Make the topping
Mash boiled turnips and potatoes with butter, boiling milk, and Worcestershire sauce.
Bake and serve
Put the mince in a deep dish and cover with the mashed turnip and potato mixture.
Bake in a very hot oven at 400°F (200°C) for 45 minutes.
Serve hot with or without tomato sauce.

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 mince and gives it a rich, meaty flavour.
- Veal suet
- Adds fat that keeps the chopped mince moist and tender as it cooks.
- Eggs
- Bind the mixture so it holds together when cut and served.
- Bread crumbs
- Absorb moisture and help give the mince a firm, sliceable texture.
- Butter
- Adds fat and richness to the mashed turnip and potato topping.
- Potatoes
- Give the topping a smooth, starchy body that mashes well and browns lightly.
The step that matters
Binding the mixture with eggs and cream. Too little egg leaves the chopped liver loose and crumbly, while too much makes it dense and rubbery. Eggs set on heating and hold the mince together, so the mixture should be bound just enough to hold its shape.
Swap the onion
How well each one fits the dish's main ingredients (liver, veal, truffle, parsley, bread, pepper, egg):
- Asparagusfits better

Fit is the average pairing score against liver, veal, truffle, parsley, bread, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
