Why it works: Butter and pepper are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 85,593 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

What each ingredient does
- Beef liver (in the method)
- Is the main ingredient, cooked into thin slices that brown and firm up when fried.
- Butter
- Adds richness and flavour to the hot fat and helps the slices brown.
- Egg (in the method)
- Coats the slices so the surface binds and browns in the hot fat.
The step that matters
Fry the slices in hot fat. The fat must be hot enough to brown the coated surface quickly. Slow frying lets the liver release moisture and turn tough and grey.
