After quite awhile searching I finally found a few Tonka beans. I have read all the information I can find on them in the snuff library, though I am still coming up alittle short with transferring the scent in high quantities. I have soaked the bean in water as suggested and removed the skin (shell) in order to transfer the scent more readily (in a sealed container with the snuff and a peice of paper as a spacer), though am having issues getting a strong Tonquin bean scent as you experience with a snuff like Elmos Reserve.
Does anybody have any personal experience with this process and whether I am missing something?
