I cold smoked 2 lbs of Tillamook 2 YR Aged Extra Sharp Cheddar (cut into 1/2 lb chunks) and 3 wheels of Gouda Cheese. Hickory saw dust (Amazing Smoker), cold Cookshack Elite, set on grates, 5 hrs. Here's a picture of the smoked cheese:
Both tasted great. Nice smoke flavor. They'll pick up more smoke flavoring overnight. They would have looked better if the grates were clean. Doesn't bother me since it's strictly for home use. May consider rotating halfway through the smoke next time to even out the color (notice the cheddar).
