I try and go as natural as I can. I scrape the fresh contents out of the sac. I avoid getting any membrane in my scrapings. Then I add glyrcien to make a paste.
Mr Beav, I'm curious if prefer to use your simple green castor/glycerin lure mix freshly made, aged a month or say aged for a year?
I'm finishing up with spring beaver, low on lure but have a decent amount of fresh castors drying right now. Planning for next season so I'm considering mix some up now or waiting for a fresh catch next season.
