Add pork, broth, vinegar, honey, soy sauce, Worcestershire, garlic powder, salt, and pepper to your Instant Pot.
Close the lid, set the valve to sealing, and cook on high pressure for 65 minutes. Let pressure release naturally for 10 minutes, then quick release any remaining.
Remove the pork and shred it with two forks. Set aside.
Switch the Instant Pot to sauté. Stir together cornstarch and water, then pour into the pot and whisk.
Let it bubble for a few minutes until it thickens slightly.
Return shredded pork to the pot and stir to coat in the sauce. Taste and adjust seasoning if needed.
Serve hot on buns, over rice, or however your heart desires.
