My wife pointed out a cookie rack to replace the ones I use, now, to dry fresh sausage in the fridge after casing (the finish is beginning to flake on the ones I have, now). I looked at these cookie/bacon racks, and realized they would be perfect for my cold smoker, so I'm sizing my cold smoker to accommodate them. They are much less expensive than purpose-built racks sold by commercial smoker companies, and they nest and fit in a standard half-sheet pan. This company ships internationally.
