Just purchased a new 40 In electric smoker. Was so excited to get using it. I was at the grocery store and bought some tuna randomly to try out my new smoker because I've never done it before and I wanted to try some stuff out before I went to smoking the turkey for Thanksgiving. I Brimed it for a few hours and got cooking. I checked on it a few hours later and it was shoe leather... Did I have it too hot ? I had it on 250 for around 3 hrs. I was under the recommended cook time from a website. Going to try out some more meat tomorrow. Is there a beginner meat to try? I'll be looking on the beginner boards here in a few. Looking forward to being in the community !
