What to look for when buying tuna
Tuna is mainly sold as steaks. You may also see strips of loin for making sushi and sashimi, and paler ventresca steaks (toro in Japanese) which are cut from the fatty belly. Look for firm, dense red or dark red flesh when buying tuna loin or steaks, and make sure it is from a sustainable source – check the Marine Stewardship Council website for the latest advice. Choose thicker steaks as these will cook far better.
