Ok..this is all new to me. We purchased a masterbuilt smoker and want to smoke our t-giving turkey..note, I am having our dinner tomorrow. I am quite confused on how long to cook and the temp to do so. "MB" recommends 225°/45 min. per LB - I saw on this web-site conflicting temp. info and how long to cook per pound. I purchased a HUGE carving turkey BREAST - it weighs just over 23 pounds - so, I certainly don't want to ruin it! What is the purpose of brining? Please help me. I have NEVER used a smoker. Thank-you!
