As you know from reading my posts I eat the ground hogs that I shoot and I really enjoy them,,, so do my two daughters. The younger ones are of course much more tender than the older ones so I usually use the older ones to make ground hog pot roast or stew. Matter of fact my daughters favorite wild game meal is ground hog pot roast.
As for the smaller ones,,, I've fried them, bar-b-q'd them and broiled them and each method yielded good results. I have to admit though that the g-hog pot roast is my absolute favorite !!
As for cleaning them,,,,, just clean out the entrails as you would any game animal, skin them, cut off the feet then cut them into smaller pieces for cooking. They can be a little hard to skin until you get the knack of it, but if you use a very sharp skinning knife to help you separate the skin from the meat it goes very quickly. Once you get the hang of it it'll only take you a couple of minutes to skin them.
Give em a try,,, I think you'll be surprised just how good they are.....
