Is that a pig knuckle?
OK, I looked it up. Here's what a friend did recently, with great results. Sear it off. Place it in a pan with cut up onions, carrots and celery, a few garlic cloves, S & P. Place in oven,. Cook low and slow for several hours, the meat will be falling off the bones when done. Remove the meat. Place veggies and juice (you may want to de-grease it) in blender and purree. He put it through a strainer, but I like mine a bit chunky. He served the knuckles on a bed of mashed, and topped it with the sauce.
Practice safe lunch. Use a condiment.
