In a medium mixing bowl, add dark brown sugar (1 cup), ketchup (1 cup), fresh ginger (3 teaspoons), and garlic (4). Whisk in soy sauce (3/4 cup), pineapple juice (1 cup), and sherry (1/4 cup) until well combined and brown sugar is dissolved.
Remove and reserve 1 cup of the marinade. Cover with plastic wrap and refrigerate until ready to grill the chicken. This will be your basting sauce.

Heat the grill to medium.
Remove the chicken from the marinade and discard the marinade in plastic bags.

Notes
Don’t Forget!: You’ll want to reserve a cup of the marinade to use for basting as you’re grilling up this little bit of tropical paradise. It really sets off the flavor bells and helps whisk you away to the land of tiki torches with every bite.
Timing: Now, let’s talk about the elephant in the room – the marinade time. I know that 24 hours seems like a long time, but your taste buds will appreciate your cooperation here. Besides the awesome flavor imparted by the pineapple, it also helps tenderize the meat into juicy succulent submission.
