I picked up 2 slabs of St Louis spare ribs at Costco. They were already seasoned but I added mustard and additional seasoning.
I smoked them without foil for 3 hours @ 240. Then foiled with apple juice for 2 hours. I removed the foil, sauced and smoked for another 30 minutes.
Lumberjack sweet wood blend mixed with hickory.
They turned out great. I usually smoke baby backs but I'm starting to like spares better.
