Why it works: Liver and pork are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,606 recipes. Both carry 1-nonanal, which smells fatty, waxy. The science ↓
Baked Calves' Liver
Ingredients
Directions
Bake the liver
Lard the liver with fat pork and place it in an iron pan with water or stock.
Bake for 45 minutes, basting often.
Remove the liver from the pan and set aside.
Make the gravy and serve
In the pan, add butter, flour, salt, and pepper to the gravy.
Boil the mixture once and pour it over the liver.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves' liver
- The main dish, becoming tender and moist as it bakes in liquid.
- Fat pork
- Larding adds fat that keeps the lean liver moist during baking.
- Flour
- Thickens the pan juices into a smooth gravy as it cooks with the butter.
- Butter
- Adds richness and flavor to the gravy and helps the flour blend smoothly.
The step that matters
Boil the gravy only once. Liver is delicate, and flour-thickened gravy can turn lumpy or thick if it is over-boiled or reduced too far. A single brief boil thickens it while keeping it smooth and pourable.
