hey every one I am doing 2 racks of spares only cause they were on sale and I'm broke. I don't really like spare ribs cause they tend to be real fatty and tough. I trimmed them down to st. Louis and trimmed off a lot of the extra fat. Now the last time I smoked spares was before I found all of you great people here on this great site. So I really hope they turn out better than the last few tries. I plan on doing the 3-2-1 and I have all the trimmings in the smoker as well. I have the tem at about 230* and the membrain is pulled off the ribs. Is there any thing I'm missin?? what should I be doing with the trimmings??
