What each ingredient does
- Liver
- Provides the main protein and a rich, savory body to the dish.
- Onions
- Caramelize when fried, adding sweetness and browned flavor that complements the liver.
- Bacon fat
- Conducts heat for frying and adds a smoky, savory richness to the liver and onions.
The step that matters
Frying the liver until cooked through. Liver turns tough and grainy if overcooked, but undercooked liver is unsafe to eat. Cooking it just until no pink remains balances tenderness with food safety.
