From a supermarket. Marinated it for a couple of hours in: olive oil, soy, citrus soy, teriyaki sauce, salt, pepper, mustard powder, ginger powder, garlic powder, red wine.
Cooked on the grill flesh side down, then skin side down, flesh side up until it reached 140 Fahrenheit in the thick end. Basted with the marinade.
A delicious medium well (how we like it) nice and juicy. Even the skin was delicious and infused with the marinade. pl
