I would think you could also do them like salt pork. A layer of salt then smelts then salt and smelts just keep doing that in a glass jar then cover with water. I took a trip up to Aziscohos yesterday just to do a little scouting roads are good I did get to Aldridge brook but couldn’t find the road to Lincoln. I stopped at my wife’s uncle’s camp and he said the smelts haven’t really started to run much yet up there.
