Corporal Kokanee I did a post on this a little while back the oil is the easy part you just boil it water/oil don't mix let it cool wola oil. problem it goes ransied over a short time I even processed it like you do canning thats fine but once it open I just couldn't find a solution to stop it from going bad. there is some type of additive needed like mineral oil or a nitrate 100% oil is just to pure. a know pro cure does a tuna oil I know friends use tuna oil alot at GP have good success I fish different places and have not had personnel good results. I was breaking it down for SALMON FISHING LIKE APPLY IT IN MY roe.
