Hey guys first post, My wife got me the 30" MES for X-mas and I smoked 2 racks of ribs in them this sat. Tasted pretty good, we both got stomach aches thou about 2 hours later. Idk if it might have been to much smoke? I know they were cooked all the way. They feel off the bone anyway, I put about 3 cups of hickory in periodical for the first 2 hours. The last hour I did not add any and then I wrap them in foil and put them back in for 1 more hour. Did I do something wrong? Also yesterday I cleaned out racks and all the food drippings. I ran some wood chips in to try season it some more. I noticed alot of yellow smoke.. idk what to do about that? Any advice will be great thank all.
