Never ate a ground hog.....
But collected a nice young rockchuck. Cleaned and saved the back half. There wasn't much to the front half.
I lived at the time, next to a drive in theater and figured I'd cook the chuck on the hibachi and watch the movie. I snaked wires from the closest parking spot so I could hear the audio too.
That little sucker muscled up like the Hulk. I kept cooking and it kept muscling up.
When done it had great flavor but was unchewable. Texture of and inner-tube, literally.
I'd suggest doing what the folks do in Oak Harbor, Ohio for muskrat days.
Pressure cook the darn thing till its tender then do something fancy with it. Maybe BBQ or something.......
