Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
To Roast a Calf's Liver
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the liver
Wash the liver thoroughly and wipe it dry.
Cut a long deep hole in the side of the liver.
Stuff and bake
Stuff the hole with breadcrumbs, bacon, chopped onions, salt, pepper, butter, and the egg.
Sew or tie the liver closed and lard it over.
Bake in a 350°F (175°C) oven, basting frequently.
Serve with gravy and currant jelly.

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 carries the stuffing.
- Breadcrumbs
- Absorb juices from the stuffing, keeping the filling moist and binding it.
- Egg
- Binds the stuffing together so it holds its shape during baking.
- Bacon
- Adds fat and savory flavor that seasons the liver from inside.
- Butter
- Adds richness and moisture to the stuffing as it melts.
The step that matters
Basting frequently during baking. Liver is lean and dries out quickly in heat. Regular basting with its own juices and fat keeps the interior moist and the surface from toughening.
