I got a Masterbuilt electric smoker for Christmas and bought a pellet tube to do cold smoking and such. Today I tried to cold smoke a block of Tilamook cheddar and a 1lb block of pepper jack. After 1.5 hours it was looking great! Pellet tube was smoking great, no melting, oil seeping from the cheese. I put cheese on top right, tube on bottom left. As far away as possible. Smoker was off and just used as a vessel to smoke in. At 3 hours I went and checked and WOW! The cheese had melted some, was black, formed a crust around the outside and was gooey in the middle. What did I do wrong? I cut a few small chunks to try tonight and they are in the pic. The blocks got wrapped and put in the fridge from what ive read makes the smoke go through the whole thing. Either way I know this isn't how it's supposed to look. Help. Please!
