Remove large items to a colander over a bowl to catch drippings. Don’t give the bones to your dogs – they have become very brittle. Bone-free meat scraps are fine. Filter out the remaining solids using cheesecloth, muslin, old clean t-shirts, a chinois, etc., whatever you have handy. Ladle through the filter into another pot. How well you filter it is a matter of taste but you sure don’t want to keep any bone bits. Press or squeeze out and save all the liquid you can before discarding the solids.
