Nam put out the call on FB for fresh lamyai (longan) branches that I want to try for smoking meats, and a good friend came through.
Her dad cut off some branches from their trees in Ubon Rachathanee and sent them back with her this weekend.
Seeing as how imported apple wood chips cost about $30 US for a 5 lb bag, this should be a great alternative. Thanks, Jay (from J)!!
