My favourite way of prepping JKP is to slice it very thin, rubbing it out to a fine shag, packing the bowl fairly loosely. Some enjoy it sliced thick, and cube-cut. It's fun to play with different preparations and seeing just how differently it behaves. It's also fun, all these months later, to see how wildly divergent it is from its ready-rubbed counterpart. When first produced, the two forms are identical, but the change over time from all the extra surface area, and the different fermentation that results, is dramatic. Even after a few weeks, it's hard to believe they're the same blend.
