First run on my smoker was my first time EVER cooking ribs in any method. Giving it the second run around this time. St Louis style, great butcher in the neighborhood took care of membrane for me at the shop. First time Ive gotten pork from them, but their beef is always top notch. Will keep you updated, as I will be using 2-2-1 method this time. Last time ended up being more like 2.5-1.5-.5 due to I thought 3-2-1 was what I was looking to use on the St Louis style.
