Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Main protein; browning on the outside sets a savoury crust while the inside stays tender.
- Butter
- Fat that conducts heat in the pan and adds richness and browning to the liver.
- Lemon
- Juice adds acidity that brightens the rich, savoury flavour of the liver.
The step that matters
Cook until browned on both sides. Liver is easily overcooked, which makes it dry and grainy. Searing over medium heat browns the surface through the Maillard reaction, so the interior can stay tender and pink in the middle.
