Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
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
Cut a hole in the liver and stuff it with bread crumbs, herbs, onion, salt, pepper, butter, and egg.
Sew up the liver and wrap it in a veal caul.
Roast and serve
Roast it in a preheated oven at 350°F (175°C).
Serve with brown gravy and currant jelly.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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, cooked whole inside the wrapping.
- Bread crumbs
- Absorb moisture from the stuffing, helping it stay soft rather than dense.
- Egg
- Binds the stuffing so it holds together when cooked.
- Butter
- Adds fat and richness to the stuffing and helps browning.
- Onion
- Adds sweetness and aroma to the stuffing as it cooks.
The step that matters
Sew up the liver and wrap it in a veal caul. If the opening is not sealed tightly, the stuffing can leak out during roasting. The caul helps hold the liver together and keeps it moist in the oven.
Swap the onion
How well each one fits the dish's main ingredients (liver, bread, pepper, butter, egg):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Onionthe original
Fit is the average pairing score against liver, bread, pepper, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
