Seared Sesame Tuna Steaks

1 c. dark soy sauce
1 c. honey
¼ c. dry wasabi powder
2 (app. 8 oz.) sushi-grade tuna steaks
¼ c. white sesame seeds
¼ c. black sesame seeds
2 Tbsp. canola oil
Wasabi aioli, optional

In a non-reactive (glass) bowl, whisk together the soy sauce, honey, and wasabi powder. Place the tuna in a glass baking dish and pour the sauce around the fish, moving the fish around to coat evenly. Marinate the tuna up to 4 hours, turning the steaks halfway through marinating. Remove the tuna from the marinade and discard the marinade. On a plate, combine the sesame seeds and coat both sides of each tuna steaks with the seeds, pressing gently so that they adhere.
In a non-coated or cast iron frying pan, heat canola oil on medium heat and place the tuna steaks in the frying pan when the oil is hot. For medium rare steak: cook for 2 - 4 minutes, flip and cook for another 2 - 4 minutes. Slice the tuna against the grain and serve drizzled with a little bit of wasabi aioli. Makes 4 servings
