01 - Whisk together soy sauce, brown sugar, water, rice vinegar, sesame oil, ginger, garlic, gochujang, and grated pear in a medium bowl until fully combined.
02 - Place beef chunks in the bottom of the crock pot. Pour the prepared sauce over the beef, ensuring all pieces are evenly coated.
03 - Cover and cook on low heat for 6-7 hours, or until beef becomes incredibly tender and shreds easily with a fork.
04 - Remove beef from the crock pot and shred using two forks. Set aside while preparing the sauce.
05 - Skim excess fat from the remaining sauce in the crock pot. Mix cornstarch with 2 tablespoons cold water to form a slurry, then stir into the sauce.
06 - Return shredded beef to the crock pot and stir to coat in the thickened sauce. Cook on high for 15 minutes until sauce reaches desired consistency.
07 - Serve hot over cooked rice, garnished generously with sliced green onions and toasted sesame seeds.
