Microwave, coffee warmer, heat gun, just leaving some flakes on my dash board, or just leaving the tins open all the time... whatever it takes to dry it out. Sometimes I don't even dry it, sometimes I just load the pipe and let it set there overnight to get a tad bit drier. I'm not dogmatic about it. Some times I even put some in a grinder and take it down to finer cut. Variety is the spice of life.
But, I just pack a little tighter for drier or finer tobacco.
Try things, branch out, or not. Whatever floats you boat.
