I mentioned this in a recent post to a turbo ribs thread, but did some more research and figured this was worthy of its own thread.
Anyway, last spare ribs I cooked was another 3 slab pack from Costco. This time, Swift Premium. This was one annoying cut of spare ribs. All the slabs had multiple long strands of cartilage perpendicular to the rib bones at the top or bottom of the slab (I'm not which which end is up)...and most of the rib bones were only as long as about half the width of the slabs. Previous spare ribs I've cooked were not like this.
So, I was back in Costco today and examined several packs of St. Louis cut spare ribs. I knew Costco carried two brands, but couldn't remember their names...so I made note, the bad one is Swift Premium. The good one is Farmland Foods. Examining several packs of each, now that I knew what to look for, I could clearly see the perpendicular strands of cartilage and short bones in all the Swift Premium racks. The Farmland packs had longer bones and in most of them, there appeared to be none of this perpendicular cartilage.
I'm wondering if others have noticed this...and if you normally buy Swift Premium St. Louis style ribs, do you do extra trimming before cooking?
