Feature: Great for hot or cold smoking salmon, bacon, eggs, cheese, butter, and much more. Can be used with almost any grill or smoker. This style of cold smoke generator looks like a maze. In essence you fill the mesh channel with wood shavings, light the tea light candle at the outer end which in turn gets the wood shavings to smoulder. Once the wood shavings have taken light ,then you extinguish the candle and inch by inch the shavings smoulder and release smoke. You may not be able to guarantee purity of the wood If produced by chainsaw then they could be contaminated with chainsaw oil and so taint the flavour of you food.
