Now that's some real blending going on there. I think pressure, oven-ing, combined with aging, constitute real blending. What I do, maybe some slicing, rubbing out, grating and working out proportions of the base and various condiments is properly called mixing.
Real blending, working out all of that processing, and then maybe doing this a dozen, or dozens of times, to get the process just right to formulate a blend, makes blending a real profession.
I'm often surprised and pretty pleased that just mixing creates some surprisingly good smoking experiences.
The work of blending makes the price of a tin of pipe tobacco not seem bad at all.
