My grandma and I used to make porcupine meatballs all the time growing up. Anytime I was staying there I always requested we made them. Now that I have been diagnosed I hadn't had them in a while since the original recipe we used called for bread crumbs. I decided to do my own modification to it and instead of using any bread crumbs I had the binder be all rice which turned out actually quite good! Here's the recipe below of you want to give it a try. Believe me they are worth it, three of us almost dusted our batch the first night.
1.5 pounds ground beef
1 small onion, minced
1 cup uncooked rice
½ teaspoon salt
Pepper to taste
2 cans tomato sauce
2 cans full of water
Mix ground beef, onion, rice, egg, and seasonings. Shape into balls about the size of golf balls, and place in a greased casserole dish. Pour over tomato sauce diluted with water.
Bake in a 375* oven for 1 hour.
Half way through we ended up turning all our meatballs. I feel this is a good idea to make sure none of the rice gets crunchy. You can also add more liquid at this point if needed.
