This page provides step by step instructions for cleaning tuna for the table. This method produces boneless skinless steaks of excellent quality.
Step 1. Wash the tuna and lay it out on a table.
Step 2. Cut along the midsection of the fish's side back to the tail and down the back close to the dorsal fin.
Step 3. Lift the loin section and cut free.
Step 4. Cut and remove the flank section in the same fashion.
Step 5. Lay out a section and begin cutting parallel to the table just under the skin.
Step 6. Follow thru cutting the skin from the meat. Finish by trimming the dark meat
from the loins and steak up if necessary. Wash the steaks or loin sections,
bag and put on ice immediately.
