In large pot, boil cabbage whole until tender enough to remove leaves. (Cut Core before boiling).
Place in cold water in sink. When cool enough to handle, remove leaves and let float in water.
Mix hamburger and rice, add salt and pepper to taste. Place the 2 ham hocks in bottom of pot. Roll large golf ball size hamburger mixture in cabbage leaves and stack on top of hocks. Cover with water just to the top of rolls. Don't go above the rolls with water. Spread the sauerkraut over the top of rolls and bring to a boil. As soon as it boils, reduce heat to simmer and cover for at least 6 hours. (Leave ham hocks in pot)Serve with mashed potatoes for an ultimate taste sensation. Very easy and the final product is awesome! No tomatoes? WOW! Hope you enjoy as much as we do!
