Around here (this climate) this is a usefull and free way to preserve root crops
Quote: Clamping offers a simple and effective way to store many common root crops such as carrots, potatoes and beetroot. It works on the principle that roots come from the ground, and therefore are best kept in the ground. Simple really.

the info here is good IMO http://nchfp.uga.edu/how/cure_smoke.html

I agree with Cat that fish to be smoked in general should be faty, but I love smoked perch when eaten warm directly out of the hot smoker oven, it's not at all dry/jerky new cooked and fresh, only when it's stored.

My favorit wood for smoking is fresh cut juniper with needles/berrys still on.

and/or with fresh cut ling (The Norwegian National flower R�sslyng)

it makes the best of flavours and fumes IMO
