My electric smoker calls for solid wood hunks so that us what I have been using - a 2 oz chunk per batch. I have been using a lot of apple wood lately for my venison and antelope jerky and I don't presoak the wood. On my smoker (Amerique) it takes about 3 1/2 hours at 200 degrees. I like my jerky thin so my jerky slices start no thicker than 1/8" before marinating it in Yashidas and I like to leave it in the marinade for at least 24 hours. I sprinkle on black pepper and red pepper (if I want it hotter) when the jerky is laid out on the racks right before it goes in the smoker...
