Step 1
Whisk together vinegar, soy sauce, garlic, olive oil, brown sugar, and crushed peppercorns in a medium bowl until sugar is dissolved. Stir in bay leaves.

Release pressure using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid. Using tongs, transfer chicken thighs to the prepared baking sheet, skin-side up. Select Saut? function and cook until sauce thickens, 3 to 5 minutes.

Step 6
Set an oven rack about 6 inches from the heat source and preheat the oven's broiler to high.
