1. In a mixing bowl, combine soy sauce, olive oil, lemon juice, sesame oil, molasses, cayenne pepper, ginger, and garlic.
2. Pour the marinade over the tuna steaks in a large resealable bag or airtight container. Allow steaks to marinate for 20 minutes at room temperature.
3. Preheat a nonstick skillet over medium-high heat. Remove the steaks from the marinade and place them in the heated pan, shaking the pan gently to avoid sticking. Cook for 1 ½ minute before flipping. Cook for another 1 to 2 minutes on the other side, or until the tuna steaks are done to your liking. The temperature should read 140 degrees F on an instant-read thermometer put into the center (60 degrees C).
4. Serve your delicious tuna steaks and enjoy!
