Step 1: Prepare the Liver

Rinse the liver under cold water and pat dry.

Trim away any connective tissue or membranes.

Slice into even pieces if necessary.

Step 2: Soak (Optional)

Place liver in a bowl with milk.

Soak for 30–60 minutes.

This helps reduce bitterness and creates a milder flavor.

Remove onions and keep warm.

Step 5: Cook the Liver

Increase heat to medium-high.

Cook liver for:

2–3 minutes per side for thin slices
3–4 minutes per side for thicker slices

Avoid overcooking, as liver becomes tough and dry.
