So, Smoking the Canadian Bacon as I type. Being new to the MES, I struggled with using Hickory Chips (which were actually a blend with Alder and more sawdust than chips) vs Hickory Chunks. I was worried that the chunks would not smoke at the 170-180 I was smoking at. Anyway, to get the chunks to fit, I had to split them to about 1in x 1in x 3 in sticks. Man NO problem with smoke at 170. Even to the point that I was initially worried about too much smoke, but it calmed down to a nice steady thin stream. My last smoke I used pellets, but they tended to be too much smoke initally, and then burn out quick. My first load of stick has lasted over an hour. Way cool.
