i'm in CA, and it's not the desert here, but it's pretty dry humidity wise. I wish i had a basement, not many homes here have them. i will look into the book. i was in a few chocolate shops over the weekend, and most of them are just storing them on trays, covered losely with plastic wrap. the chocolates i did open up, some had mold on the cap part of the mold. some had mold on the outside of my enrobed chocolates. i had them stored in a kitchen area and it did get up to about 87f here last week. i was very surprised that some got mold, and the others that didn't lost all flavor.
