Just wanted to post my first go at processing bear fat--overwhelmingly positive, thanks to lots of good info above.
So... this spring I glassed up a bear near the bottom of a big canyon. My buddy bailed down in there and by last light we were standing over his beautiful 200ish lb chocolate boar. We were about half a mile from my truck in ballistic distance, but 1300 ft below it and did not want to make more than one trip out. This precipitated an earnest conversation about what parts of the bear to pack out. We left the hide (kinda rubbed off), but once we started cutting into the pure white fat on the back, there was no way we were leaving any of that for the magpies.
In the end, we wound up with about 15 lbs of fat between us. I basically followed cjl32's advice (above) about rendering my half of it. The only deviations were that I ground all the fat first while it was half frozen to increase yield (as recom
mended by Clay Newcomb/Meateater) and rendered it in a crockpot rather than over a burner. I'd recommend the crockpot route for ease--you can basically just set the ground fat in there with a little water and come back 8-12 hours later and it's done and you don't have to worry about it burning or sticking as you might over a burner. I covered my crockpot with a window screen rather than a lid to facilitate evaporation of the water, while keeping off the flies/yellowjackets. But my crockpot would only hold half the fat at a time, so I had to do it twice. Anyway, I rendered about 7 lbs of fat into about 64oz. of pure white lard.
Just working with it made me see why people use it as hand cream. But I was way more interested in eating it--and so far it has been great! I've used it as fry oil to make french fries for poutine (with bear bone broth gravy) and as fry oil to cook chicken-fried bear tenderloin. Both disappeared fast! I haven't yet convinced my wife (the baker in the family) to use it in pie crust, but I'll get her on board. Or maybe i'll use it to make tomales...
I also wanted to circle back to the rumor that un-rendered bear fat will go rancid in the freezer:
I’ve heard this as well but I never had that problem. i just recently cooked a bear roast that was extra fatty and had been in the freezer over a year. It was great! The burger with bear fat in it was in the freezer at the longest probably 6-7 months and was great. I’ve only done this with 2 bears and both were fine. Not sure what the difference would be.
FWIW, this is what Meateater folks had to say about keeping the fat in the freezer:
"According to Clay you can store un-rendered or rendered bear fat in an airtight container for up to 6 months in the freezer to utilize the fat before it starts burning.

Pork fat is the same -->

Happy hunting & fishing,"
So it seems that un-rendered bear fat stays good for 6 months to a year just like pork. Meat usually doesn't make it that long in my freezer anyway, so this kinda opens the door to a lot of good cooking options because (unlike deer/elk) bear fat is delicious!
Less than 2 months to fall bear season!
