Place wings in a large bowl and set aside.

In a saucepan combine jam, vinegar, soy sauce, garlic and pepper. Bring to a boil and boil for 1 minute. Add raspberry mixture to bowl with wings and toss to coat. Cover and refrigerate for 4 hours.

Line a 15 x 10 x 1 inch rimmed baking sheet with aluminum foil and spray foil with nonstick spray. Preheat oven to 375 degrees F.

Reserving marinade, place wings in single layer on baking sheet.

Bake at 375 degrees F for 30 minutes, turning once.

Meanwhile, bring reserved marinade to a rolling boil and boil for 1 minute. Reduce heat and simmer, uncovered for 10 - 15 minutes.

Brush marinade over wings and bake 20 - 25 minutes longer, turning and basting once, or until check juices run clear.
