I made 2 gallons up last year, using the same amounts you discribed(1 cup per gal). I used beaver meat cut into chunks and I added the borax like salting fish or meat.(a layer of beaver chucks and a coating of borax until the jar was full. I stored it in a crawl space under the house all last winter and summer until I took it out this fall in Nov.
Alas, I never got the chance to try it coyote trapping, but the day I lifted it out from under the house for use my dog was sound asleep in the bedroom at the end of the hall, when I opened the lids to take alook the smell brought him from a sound sleep and into my lap in an instant. And he loves it.
Getting it ready for use, one jar I set in an old fridge outdoors that I use for storage.(and I never checked it since) The other jar I left sitting in a back corner of the laundry room where I could put it in smaller containers and where it stayed warm, In that jar the moisture came out of the meat and turned into a nice brown gravy looking juice. As I said I never gave it much of a try on the line but the meat still has that nice beaver meat smell so it should work!
