Pour the beef broth into the pot and scrape up any browned bits from the bottom. This prevents a burn notice.
Add the soy sauce, brown sugar, rice vinegar, sesame oil, garlic, ginger, and white pepper to the pot. Stir well.
Return the seared beef to the pot. Do not stir after adding the beef.
Secure the lid and set the vent to Sealing. Select Manual/Pressure Cook (High Pressure) for 3 minutes.
When the cooking cycle finishes, allow a Natural Pressure Release (NPR) for 5 minutes, then carefully perform a Quick Release (QR) for any remaining pressure.
Remove the lid. Remove the beef from the pot using a slotted spoon and set aside.
In a small bowl, whisk together the cornstarch and cold water to create a slurry.
