OK, this is probably a terrible question but I am too new and inexperienced to know the answer. I have read how to keep constant high heat with the minion method. Now how do you measure that heat? I smoked my first chicken last weekend and tried using a meat thermometer to measure the temperature in the smoker. My lid does not sit flush with the smoker leaving a gap. I just stuck the probe in the gap and watched the temp rise. My problem is I don't believe what the thermometer is telling me. I NEED HELP!
