So we have all seen over the past little bit that less and less stores sell full slabs of spares. They trim them and you have to buy rib tips separately. I have avoided buying these pretimmed ribs until today, I wasn't able to make it in time to my go to supplier. Promised my Mom ribs for her birthday so I had to give in and buy these for tomorrow. Has anyone tried these and how did you like them ? Also since they are already trimmed, do they also pull the silver skin? Guess I will fins out in the AM. Any feedback is appreciated.
