Haven't been able to find large spare rib slabs other than Walmart so far and I am not buying the Wally slabs. They don't even look good in the package. Floating in solution. One of the stores I want to last night had advertised "Pork Back Ribs" at 3.99/lb. I assume these are baby backs. They were all trimmed up and cut into single serve pieces already. I called a local market today and they told me they were getting slabs of spares in tomorrow. 3 to 4lbs per slab at .99 per pound!! Untrimmed. So being new at this and have not shopped extensively for smoker meats is this a super deal? Should I stock up the freezer? How long will these stay in the freezer before you should use them up? Supposed to reach near 30 degrees here Sunday so I am thinking a slab of spares before the big game.
