Greg Pease's FAQ
Since I'm smoking a lot of very aromatic stuff lately, I've encountered the same thing River. I'm using two techniques depending on how moist the tobacco is and how it's cut. The thicker cuts (or if it's just really sticky cased) I leave for a couple days in a stoneware dish with a loose-fitting lid--it's very dry here right now and this seems to dry it out at a very nice rate while keeping all the lovely aroma in. Finer cuts I simply place on a paper plate and allow to air-dry for as long as it takes to get the right feel between my fingers.
Also, have you checked out the different packing methods? There's a recent thread on here about those, and the air pocket method helps a lot with the goopy stuff.
It takes practice, but not a science degree--I'm managing a much better consistency than I was 9 months ago. Another reason why pipe smoking is such a wonderful pastime is its reliance on our tactile senses.
