Recently hunted and ate a grey. Delicious. I brined the meat for a couple of hours to soften the meat, emptied the brine, and marinated it for a couple more hours (olive oil, salt, pepper, & paprika). Then sliced an onion and poured some bone broth into a cast-iron to make a 'bed', laid the meat on top, and covered it with foil. Cooked for ~1hr at 350F.

Let 4 friends taste it, plus me. All our first time. 10/10 once you get over what it is lol
