I remember the Pinkerton product, if we're talking about the same era. Was that the early '70s, perhaps? Anyhow, I remember once back then taking a low power microscope to look at the tobacco flakes of Half & Half. I swear they were mixing in chopped homogenized leaf in the product. Not the entire pouch, just some mixed in with real, or whole tobacco. Same thing with Paladin Black Cherry at the time, the worst tobacco ever. I was suspicious because homogenized leaf makes my throat feel funny, even though I don't inhale.
But H & H at its best was quite tasty. I don't quite get the same aroma from the current product, but maybe it's just me. It used to leave a very distinctive scent (cinnamon-like, to my nose) in any room it was smoked in--or in my case, the cab of a 988 Cat loader. Today, not so much. Anyhow, the perique addition sounds interesting, and I just may try it.
