Roasted Corned Beef Brisket with Mustard Cream Sauce
Originally intended as a St. Patrick's Day dinner and a departure from the traditional braised method of preparing Corned Beef, served with the Kitchen Tapestry recipe for Mustard Cream Sauce.
Corned Beef & Cabbage, the traditional St. Patrick’s Day supper, is about as Irish as Chop Suey is Chinese. To be specific, Corned Beef & Cabbage is not an Irish dish, it's an Irish-American dish. It was born in New York City during the European immigrant migration of the late 19th and early 20th Centuries, when Irish New Yorkers were able to buy corned beef briskets from Jewish delicatessens to celebrate St. Patrick's Day, which is sort of ironic if you stop and think about it.
“Corned Beef” gets its name from the large grains of salt, historically called "corns" of salt, used to cure the meat. The term "corn" in this context comes from an old English word for small, hard particles. This curing process preserves the beef and gives it its distinctive salty flavor.
The practice of "corning" meat dates back centuries, with early methods being particularly popular in Ireland and Britain before becoming widely associated with Irish cuisine and, later, with Irish-American traditions.
The traditional way of slowly simmering a Corned Beef in a savory broth is not entirely a bad way of preparing it. It's easy and you can't really screw it up. But I experimented with a technique that first braises the meat, mostly to loosen it up and dispatch some of its saltiness; then roasting it with a basting sauce; and finally broiling it with a mustard/brown sugar schmear to give the meat a final golden, crusty exterior. I serve it alongside the Kitchen Tapestry recipe for Mustard Cream Sauce, with some added apple cider vinegar to round out the flavors and provide a bit of tang. The recipe for the cream sauce is posted below for convenience; just add 1/8 cup of apple cider vinegar to the recipe as written.
Along with the Kitchen Tapestry recipe, Fried Cabbage with Bacon & Caraway, you have a very non-traditional way to serve the traditional Corned Beef and Cabbage supper for St. Patrick’s Day or any other time of year.
