When Chef Dean Fearing was Executive Chef at the Mansion on Turtle Creek in Dallas, Texas he showed this recipe on a local television show. This sauce can be used as a BBQ mop sauce but the one he showed that I used was pan searing Beef Filets in this sauce just until desired doneness. I did make a couple of adjustments. The original recipes called for 1 cup malt vinegar which you will see I tweaked. Also, instead of the thyme I used parsley and added grated garlic to taste. This is truly wonderful but you must use Shiner Bock beer. I thought I lost this recipe and it is no longer posted. Just found it and putting it here for safe keeping.
