I cannot take full credit for this as I found a lot of the information in other places. However, I have done this several times now with really nice results. If you wish to attempt your will need:
> A cheap electric soldering iron that has never been used. Harbor Freight sold me mine for about $3 bucks.
> A Plastic storage tote.
> A rack of some sort for the cheese to sit on. (Mine is a Wal-Mart plastic coated one)
> A cheap coffee cup, never used is best.
I used maple chips for the last smoke. I just placed a handful in the coffee cup, a little water and place the soldering iron in and plug in.
After about 5 min it will really start smoking. I test smoked the first time for different periods and have found that 3 to 3 1/2 hours is almost perfect.
After you smoke let sit in fridge overnight and vacuum seal as usual.
May work if you don't have another way to cold smoke!
