Saw this on the Contessa's show on the Food Network last night. She serves it with a standing rib roast. I think it has many possibilities, perhaps as a base for a dip with chipped beef? The whole-grain mustard adds great texture. I made this for Christmas to go with Recipe #95534 ("da Best" Chicago-style Italian Beef) and it was a heavenly combination. This made a lot so I took one and a half cups of the sauce, added about one cup of shredded sharp cheddar cheese and 3 chopped hard-boiled eggs. It was a lovely dip for crackers.
