Squirrel skin is very tough! But I have never had tough squirrel meat. How did you cook it? Cook it slow. My Mother would make squirrel and dumplings. Sometimes, she would just use cream of chicken, and flour dumplings, and the squirrel, and onions, garlic, and salt and pepper. But there was never any left. I don't use bullion, as it is all chemicals, and some don't even have any chicken, or beef, at all. I just use organic, broth, or make my own. Just try the squirrel and dumplings, and you'll love it. Make your dumplings, how you like them. Just don't try to cook the squirrel to fast, just like making a bow, slow and easy. She would also fry them, and that was good, but the squirrel and dumplings were my favorite.
