What each ingredient does
- Liver
- Forms the main protein and browns on the surface while staying tender inside.
- Onions
- Caramelize as they fry, adding sweetness and savory browned flavor.
- Bacon fat
- Conducts heat in the pan and adds a smoky, savory richness to the liver.
The step that matters
Frying the liver. Liver overcooks quickly and turns dry and grainy when it is cooked too long. Keeping the heat moderate and the pan shallow lets it brown while remaining tender inside.
