Did some baby back ribs last night and was ready to do the aquarium pump mod on my MES in case I had trouble keeping the AMNPS lit but it wasn't necessary. It was actually burning too quickly at one point and I had to move it and give it more of a heat shield. What a great little device. I can't imagine going back to the inconsistent smoke and high maintenance of wood chips. I had them on for about 5 hours and wrapped them in foil for the last hour or so. Mustard and Rub AMNPS smoking nicely Right before going into the foil. Pulled off and let sit for awhile then opened them up Dinner. I intended to grill some asparagus as a side but I decided to just have ribs in the end. Shame on me. Overall I'm quite pleased. This is probably my 10th smoke on the MES and the first that I didn't put any water in the water tray due to the AMNPS. I sprayed them with an apple cider vinegar and olive oil mix every hour because I was kind of concerned about dryness. I have also previously done spare but not baby backs. The spare ribs have been good but a little more fatty than I prefer. The spare ribs were definitely more "fall off the bone" but I think that I prefer the slightly firmer consistency I got this time. I might try 2-2-1 next time but I'm so pleased with the texture I'm not sure I want to deviate. I'm also considering using a rib rack and cutting the racks in half so I can fit 2 on 1 level of the smoker. I'm going to try a chicken today and see how it turns out with no water in the tray.
