I have smoked plenty of baby backs but never spare ribs. Costco had a good deal on them and I love to try new things, so guess what I'm doing this weekend. This has probably been covered somewhere before, but I looked and didn't really see it anywhere. Does it make any difference in trimming spare ribs into St. Louis style ribs. Kind of looks to me that when you trim them, you basically have baby backs so what is the point. If you do trim them, what do you do with the trimmings? I have watched video of trimming and it looks like some good meat being trimmed off. I am sure I will get some very strong opinions for doing it both ways. Let me know why you think your way is best. I promise I will post some pics this weekend. P.S. I also bought some beef baby back ribs.... but that is another weekend.
