I'm going to smoke 16 pounds of pork spare ribs on a Brinkman Gourmet electric smoker for the first time. The book says to smoke for 45 min. per pound which would take about 12 hrs. It will be about 95 F in the shade and the wind will be about 5-10 miles per hr. and I plan to keep the water pan from going dry. I know the math is correct but do I really need to cook the ribs that long?
