The duration required to prepare a substantial tuna steak on an open flame is determined by several key factors. These include the steak’s thickness, the intensity of the grill’s heat, and the desired level of doneness. A steak measuring approximately 1.5 inches in thickness will require significantly more time than a thinner cut.
Properly grilling tuna results in a flavorful and moist product. Overcooking leads to a dry and less palatable outcome. Monitoring internal temperature using a meat thermometer ensures optimal results. Furthermore, allowing the cooked tuna to rest briefly after grilling enhances its juiciness.
