What can be more comforting on a chilly autumn day than braised short ribs served over a creamy mash or polenta? After reviewing several recipes, I came up with this one. I enriched my chicken stock with veal bones that I was able to find at a nearby ethnic market. If you cannot find veal bones, then just use chicken stock or veal stock from demi-glace. I use duck fat whenever I can, so I browned the short ribs in some duck fat. To add a little brightness to the sauce, I added the zest of an orange along with some of its juice. At first this sauce just did not work, but I kept tweaking it. And when it was served over my roasted pureed cauliflower with blue cheese, it was sublime. Sorry to sound so boastful, but it was really very good. Will serve to my guy tomorrow, and the flavors will be even better. For an extra special touch at serving time, top with a gremolata of grated orange zest, a very finely minced clove of garlic, some toasted pine nuts and some chopped flat-leaf parsley.
