To prepare a the real deal korean beef ribs recipe, you'll need: 1 pound brisket, 2 lbs ground beef, 1 cup brown sugar, and 1 teaspoon kosher salt. Cut the beef into 1/4-inch cubes. Heat 1 tablespoon of vegetable oil in large skillet over medium-high heat. Add beef and cook, turning occasionally, until browned on all sides, 4 to 5 minutes. Remove from skillet and set aside. In medium bowl, whisk together 2 tablespoons of soy sauce, 1/4 teaspoon ground cumin, 1/2 teaspoon each ground coriander and ground tarragon. Pour in 2 cups of water and bring to boil. Reduce heat to medium and simmer, covered, for 30 minutes, or until beef is no longer pink in the center and juices run clear when pierced with knife. Serve with sour cream and guacamole.
