Never had the . . . pleasure. But I'm sure there's something to be done with them that our culinary friends will suggest for you.
Now, please forgive the diversion but every time I see or hear the word "pork" I'm reminded of a hilarious typo I saw in a jobs want ad many years ago. It was for a waitress and a local cafe and ended with "Must be willing to pork." Obviously, they meant "work" but can't help some smartass (not me but would have been happy to oblige...) saw an opportunity to have a little fun...
Good luck with your jowls...
Wishing to be of assistance, just Googled "Pork Jowls" and a lot of delicious ideas appeared. Go for it!
