I am working on some recipes where I need to do some braising of the meat. What is braising you ask?

The steady heat helps break down the connective tissue while the meat and the bone release their deepest, richest flavors. The key points are to brown the meat before braising and then keep a lid on tight to seal in the cooking liquid.
