My mom gave me a $50 gift card to Home Depot. I decided I needed another smoker, so I looked around the internet and found an Alton Brown video on this home-build. I place an 18.5 inch grill between the two pots. I have used this smoker for rib roast, pastrami, ribs, and turkey legs. It is the poor-mans version of the green egg, holding temperature really well. Scroll to the bottom to see the first rib roast I smoked in this contraption. Two terracotta pots... An electric burner is in the bottom beneath the pie plate. The grill is used to support a liquid pan... I had to drill out the bottom hole a little to get the cord end through. The burner has an adjustable control that I set at medium high. The expense was in the terracotta pots, so if you have some laying around or you can score them in a garage sale, you can make this smoker for under $30. Here is the first smoked rib roast after 5.5 hours.!!!
