I too, bought the book. After reading it and further investigetion, I found that there are no retail dry curing chambers. The closest you get is a wine fridge. The problem is keeping the humidity, and the temperature exact. I saw some converted fridges, with humidifiers, and lightbulbs installed on the inside. These do the job of balancing the temp and humidity. Also , I've heard of using salt, in the bottom of the fridge. Most people didn't seem to have alot of luck this way tho.
It'll be great to see what results people on here have had, or get. I did some bacon, and it turned out spectacular! Plan on doing some canadian bacon, or proscuitto next!
