you might be too late, seeing as how it's already dry, but i have no way of knowing how dry it is. and I definitely wouldn't remoisten it, you're best bet is to mold it into balls or chips when it's still pretty malleable (not wet, but pliable). I've made hash that even after being dried still has a very putty like feel to it. so i guess it all depends.
also how did you make your hash
what method did you use?
