I watched Alaska: The last Frontier the other week when the Kiltcher family was Salmon fishing and smoking salmon. Atz Lee was smoking in a homemade tepee smoker and using green Alder. They peeled the bark off and tossed it on top coals from spruce. The other family members did the same in other smokers. I was wondering if anyone has any experience with green Alder and Spruce. It is new to me. Great show!
