Shark Steaks can be strong if not prepared properly. 

To clean the Shark I cut the head off and slice down the belly carefully to remove the innards.  I leave the skin intact.  I cut the Shark Meat about 2 inches think (3 Centimeters). 

I then marinate in Italian Salad Dressing for 12-24 hours covered in the fridge. 

It is really great on grill or in a thick cast iron pan.  Any good  Seafood marinade will also work.  

My wife keeps a collection of Seafood Cook Books because she never knows what I will bring HOME!
