I made Italian wedding soup in the crock pot last night. I put small raw meatballs into the crock with chicken broth and cooked them for 6 hours on low. When I took them out, they looked cooked on outside, but when I cut into them, they were pink in color but cooked in texture, if that makes any sense. So, I put them back in for two hours on high but they looked the same. There's no way they weren't cooked --right??? Is that just how ground beef in the crock comes out??
