Mix marmalade, mustard, bourbon, garlic and red pepper flakes in a large bowl. Toss chicken wings with marinade. Refrigerated a few hours or overnight (preferably).

Preheat oven to 400°F. Cover a large cookie sheet with aluminum foil and place a heat-proof cooling rack on top of cookie sheet. Place marinated wings in a single layer on cookie sheet. Reserve leftover marinade.

Cook wings for 45 to 50 minutes or until cooked through and crispy.

While wings are cooking, place reserved marinade in a pan. Bring to a boil over medium-high heat and boil for 2 minutes (this kills the bacteria from the chicken). Reduce to low to keep warm.

Serve wings warm or at room temperature with sauce.
