Why it works: Butter and bread 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
Boiled liver
Slice the calf's liver and season with pepper and coarse sea salt.
Boil the liver until cooked nicely.
Rub a bit of cold butter on the liver and serve hot.
Roasted stuffed liver
For roasted liver, wash and wipe it clean.
Cut a long hole in the liver and stuff it with crumbs of bread, chopped anchovy, herbs, fat bacon, onion, salt, pepper, and an egg.
Sew the liver up, lard it or wrap it in veal fat, and roast it.
Serve with brown 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
- Main ingredient; its tender, rich texture is the core of the dish.
- Egg
- Binds the stuffing so it holds together inside the liver.
- Bread crumbs
- Soak up juices and give the stuffing body and a soft texture.
- Cold butter
- Adds richness and a glossy fat finish to the hot liver.
- Fat bacon
- Adds fat and savoury flavour as the liver roasts.
- Chopped anchovy
- Adds salty, savoury depth to the stuffing.
The step that matters
Boiling the liver until cooked nicely. Liver is lean and its proteins tighten quickly with heat. Overcooking makes it dry, grainy and tough, so it should be removed as soon as it is just cooked through.
Swap the onion
