I've used the leavings in the bottom of a tin, jar or bag to combine into a bowl's worth lots of times. Sometimes they are bad tasting, sometimes decent, and a couple of times were pretty good. I thought I would try something different, and start putting leaving of similar type together instead of a total hodge podge. This afternoon, I had a jar with some well aged SG FVF leavings in it. This stuff was exceptionally good, so I couldn't bring myself to dump it. I also had a jar with some well aged McClelland 5100 scraps, and while perusing the cabinet, picked those two at random. The FVF was not enough to even be a partial flake, but I still rubbed it out a little finer to somewhat match the 5100. I then dumped it in the 5100 jar and mixed it up. Together, they equaled a little over a bowl full. I loaded my Neerup, Virginia dedicated briar and went out on the back deck for a smoke, while my wife sucked on a cup of coffee. The weather is perfect at 68* and little to no breeze. After my first tamp, I was so surprised at the flavor that came through. The malty, molases flavor of the FVF mixed with the slightly sweet, traditional flavor of 5100 and produced a fabulous combination! Incredibly smooth, rich and flavorful. I thought I was in store for a decent smoke, and being frugal, but ended up with a great evening smoke. I've now got babyfood jars set up to dump Burley, Virginia, VaPer, Lat leaving individually. I'm really curious to see how the others work out.
