Common Mistakes
Overcooking
This is the biggest reason people dislike liver.
Perfectly cooked liver should remain moist.
Crowding the Pan
Too much meat lowers the pan temperature.
Cook in batches.
Skipping the Onions
Sweet caramelized onions balance the strong flavor beautifully.
Not Drying the Liver
Moist liver won’t brown properly.
Always pat it dry.
Storage
Store leftovers in an airtight container.
Refrigerate for up to three days.
Reheating
Warm gently in a skillet over low heat.
Add a splash of beef broth to prevent drying out.
Microwaving is possible but may toughen the liver.
