When I make chevre, after removing from the moulds, or if it is not dripping anymore, which is around 48 hrs, I salt the surface and sprinkle ash (by using salter). The cheese rests another 24 hrs to dry further, then I spray PC lightly. When I do otherwise I found that ash peels off. I wait for a couple of days until white mold develops, then wrap it in paper.
Here are some pictures, this my version of frosty treat :-)
