Why it works: Pepper and flour are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 50,459 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Fried Calves' Liver
Ingredients
Directions
Prepare
Soak the liver slices in saltwater for several hours to draw out the blood.
Season the liver with pepper and salt.
Fry and make gravy
Fry the liver in hot lard until cooked through, frying slowly to avoid browning the outside too quickly.
Thicken the cooking liquid with a little flour and add water.
Let the gravy boil once.
Serve
Pour the gravy over the liver and serve.
Alternatively, serve the liver without gravy.

What each ingredient does
- Calves' liver
- Is the main protein, cooked through to become tender and firm.
- Lard
- Conducts heat for frying and adds richness and browning to the outside of the liver.
- Flour
- Thickens the cooking liquid into a gravy.
The step that matters
Fry slowly in hot lard. Frying gently lets the heat reach the centre of the slices before the outside over-browns, which would toughen the surface and leave the liver dry and firm inside.
