Preheat oven to 400° F. Set a wire rack inside a large rimmed baking sheet.

Place chicken wings, vegetable oil, salt, and pepper in a large bowl; toss to coat.

Before the wings are placed in the oven, start making the sauce. Add chicken stock, balsamic vinegar, soy sauce, honey, garlic, ginger, and peppercorns in a small saucepan. Whisk to combine. Bring to a simmer. Simmer over medium heat for 12 minutes uncovered until reduced by half.

Once reduced, strain sauce and add back to the saucepan. Keep sauce heated over low while wings bake.

Place wings on wire rack and spread out in a single layer. Bake wings for 45–50 minutes, basting with sauce three or four times until the sauce is all used up.
