...and I feel like burning a little tobacco:
The bowl is from a chokecherry. I cut it off where several branches whorled from the main stem, just to add some character.
The stem is green ash. tapered to fit the bowl and set with a li'l bit of hide glue.
Finish is simply beeswax. As I played the heatgun across the wood, it browned the surface just slightly. No stain was used.
The bowl is just over an inch across, outside diameter, and 5/8" inside. The stem was drilled out with a bit of brass wire filed into a chisel point. It followed the pith of the branch perfectly.
