That's really interesting! I will have to try that with my own cherry and apricot trees. My dad grew up chewing resin from Sweetgum trees (Liquidambar styraciflua). I am going to try making some PSruce gum, too, from my Colorado Blue Spruce (Picea pungens). Spruce gum used to be made commercially, from the resin. Enjoy your resin! :D
