Guinness-Braised Corned Beef

Preheat your oven to a moderate temperature of 300 degrees Fahrenheit or 150 degrees Celsius.

Rinse the brisket under cold running water to remove any impurities, then gently pat it dry with paper towels to prevent excess moisture. Place the brisket on a wire rack in a roasting pan or Dutch oven, ensuring it's centered and even.

Generously sprinkle brown sugar all over the brisket, making sure to cover every surface evenly. Next, pour a sufficient amount of beer around the brisket, taking care not to overflow the pan. Gently pour some of the beer over the sugar-coated brisket, allowing it to saturate and stick to the meat.

Place the covered roasting pan or Dutch oven in the preheated oven and bake until the brisket is tender, approximately 2 ½ hours. To verify doneness, insert an instant-read thermometer into the center of the brisket and check that it reaches a minimum internal temperature of 190 degrees Fahrenheit or 88 degrees Celsius.

Once the brisket is cooked, remove it from the oven and let it rest for 5 minutes before slicing.
